Product Folder Sample & Buy Support & Community Tools & Software Technical Documents Reference Design LM4132, LM4132-Q1 SNVS372G – AUGUST 2005 – REVISED OCTOBER 2016 LM4132, LM4132-Q1 SOT-23 Precision Low Dropout Voltage Reference 1 Features 3 Description • • The LM4132 family of precision voltage references performs comparable to the best laser-trimmed bipolar references, but in cost-effective CMOS technology. The key to this breakthrough is the use of EEPROM registers for correction of curvature, temperature coefficient (tempco), and accuracy on a CMOS band-gap architecture allowing package-level programming to overcome assembly shift. The shifts in voltage accuracy and tempco during assembly of die into plastic packages limit the accuracy of references trimmed with laser techniques. 1 • • • • • • • • • Qualified for Automotive Applications AEC-Q100 Qualified With the Following Results: – Device Temperature Grade 1: –40ºC to +125ºC Ambient Operating Temperature Range – Device HBM ESD Classification Level 2 Output Initial Voltage Accuracy: 0.05% Low Temperature Coefficient: 10 ppm/°C Low Supply Current: 60 µA Enable Pin Allowing a 3-µA Shutdown Mode 20-mA Output Current Voltage Options: 1.8 V, 2.048 V, 2.5 V, 3 V, 3.3 V, 4.096 V Custom Voltage Options Available (1.8 V to 4.096 V) VIN Range of VREF + 400 mV to 5.5 V at 10 mA Stable With Low-ESR Ceramic Capacitors Unlike other LDO references, the LM4132 can deliver up to 20 mA and does not require an output capacitor or buffer amplifier. These advantages along with the SOT-23 packaging are important for space-critical applications. Series references provide lower power consumption than shunt references, because they do not have to idle the maximum possible load current under no-load conditions. This advantage, the low quiescent current (60 µA), and the low dropout voltage (400 mV) make the LM4132 ideal for battery-powered solutions. 2 Applications • • • • • • • • • • • The LM4132 is available in five grades (A, B, C, D and E) for greater flexibility. The best grade devices (A) have an initial accuracy of 0.05% with a specified temperature coefficient of 10 ppm/°C or less, while the lowest grade devices (E) have an initial accuracy of 0.5% and a tempco of 30 ppm/°C.

This series reference can operate with input voltages from VREF + 400 mV to 5.5 V while consuming 60-µA (typical) supply current. In shutdown mode, current drops to 3 µA (typical). The LM4132 is available in five grades from A and E. The best grade devices (A) have an initial accuracy of 0.05% with a specified tempco of 10 ppm/°C from –40°C to 125°C. The grade devices (E) have an initial accuracy of 0.5% with specified tempco of 30 ppm/°C from –40°C to 125°C. 7.2 Functional Block Diagram VIN VBG BANDGAP CELL ± Q1 ILOAD + VREF EN § R1 · VBG ¨ 1 ¸ © R2 ¹ R1 COUT R2 7.3 Feature Description The LM4132 can be remotely operated by applying an EN voltage between 65% of VIN, and VIN. The LM4312 can be remotely disabled by applying an EN voltage between 0 V to 35% of VIN. The EN pin can also be strapped to VIN, so VREF is active when VIN is applied. 7.3.1 Short Circuited Output The LM4132 features indefinite short-circuit protection. This protection limits the output current to 75 mA when the output is shorted to ground. 7.3.2 Turnon Time Turnon time is defined as the time taken for the output voltage to rise to 90% of the preset value. The turnon time depends on the load. The turnon time is typically 33.2 µs when driving a 1-µF load and 78.8 µs when driving a 10-µF load. Some users may experience an extended turnon time (up to 10 ms) under brownout conditions and low temperatures (–40°C). 20 Submit Documentation Feedback Copyright © 2005–2016, Texas Instruments Incorporated Product Folder Links: LM4132 LM4132-Q1 LM4132, LM4132-Q1 www.ti.com SNVS372G – AUGUST 2005 – REVISED OCTOBER 2016 Feature Description (continued) 7.3.3 Thermal Hysteresis Thermal hysteresis is defined as the change in output voltage at 25ºC after some deviation from 25ºC. This is to say that thermal hysteresis is the difference in output voltage between two points in a given temperature profile. An illustrative temperature profile is shown in Figure 47. 125oC VREF1 25oC Time VREF2 -40oC Figure 47.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The LM4132 family of precision voltage references can deliver up to 20 mA without an output capacitor or buffer amplifier. The LM4132 is ideal for battery-powered solutions, with a low quiescent current of 60 µA, and a low dropout voltage of 400 mV. The LM4132 enters the shutdown mode (3 µA, typical) when EN is 0 V. 8.2 Typical Applications 8.2.1 LM4132 Typical Application Input 5V VIN Output 2.5V VREF CIN* * COUT LM4132 Enable EN GND 8.2.1.1 Design Requirements For this design example, use the parameters listed as the input parameters. • VIN > VREF + 400 mV (ILOAD ≤ 10 mA) • ILOAD ≤ 20 mA • The LM4132 is enabled when 65%VIN< VEN ≤ VIN. VEN cannot be greater than VIN; otherwise, the device does not operate correctly. • The devices is disabled when 0 V ≤ VEN ≤ 35% VIN. 8.2.1.2 Detailed Design Procedure The foundation of any voltage reference is the band-gap circuit. While the reference in the LM4132 is developed from the gate-source voltage of transistors in the device, principles of the band-gap circuit are easily understood using a bipolar example. For a detailed analysis of the bipolar band-gap circuit, refer to AN-56 LM113 1.2V Reference (SNVA514). 8.2.1.2.1 Supply and Enable Voltages To ensure proper operation, VEN and VIN must be within a specified range. An acceptable range of input voltages is calculated by Equation 2: VIN > VREF + 400 mV (ILOAD ≤ 10 mA) (2) The EN pin uses an internal pullup current source (IPULLUP ≊ 2 µA) that may be left floating or triggered by an external source. If the device is not enabled by an external source, it may be connected to VIN. An acceptable range of enable voltages is given by Figure 4. See Electrical Characteristics LM4132-1.8 (VOUT = 1.8 V) and Figure 3 for more detail. The device does not operate correctly for VEN > VIN. 22 Submit Documentation Feedback Copyright © 2005–2016, Texas Instruments Incorporated Product Folder Links: LM4132 LM4132-Q1 LM4132, LM4132-Q1 www.ti.com SNVS372G – AUGUST 2005 – REVISED OCTOBER 2016 Typical Applications (continued) 8.2.1.2.2 Component Selection A small ceramic (X5R or X7R) capacitor on the input must be used to ensure stable operation. The value of CIN must be sized according to the output capacitor value. The value of CIN must satisfy the relationship CIN ≥ COUT. When no output capacitor is used, CIN must have a minimum value of 0.1 µF. Noise on the power-supply input may affect the output noise. Larger input capacitor values (typically 4.7 µF to 22 µF) may help reduce noise on the output and significantly reduce overshoot during start-up. Use of an additional optional bypass capacitor from the input and ground may help further reduce noise on the output. With an input capacitor, the LM4132 drives any combination of resistance and capacitance up to VREF / 20 mA and 10 µF, respectively. The LM4132 is designed to operate with or without an output capacitor and is stable with capacitive loads up to 10 µF. Connecting a capacitor from the output and ground significantly improves the load transient response when switching from a light load to a heavy load. The output capacitor must not be made arbitrarily large because capacitor selection affects the turnon time as well as line and load transients. While a variety of capacitor chemistry types may be used, it is typically advisable to use low equivalent series resistance (ESR) ceramic capacitors. Such capacitors provide a low impedance to high frequency signals, effectively bypassing them to ground. Bypass capacitors must be mounted close to the device. Mounting bypass capacitors close to the device helps reduce the parasitic trace components thereby improving performance. 8.2.1.2.3 Temperature Coefficient Temperature drift is defined as the maximum deviation in output voltage over the operating temperature range. This deviation over temperature may be shown in Figure 48: Temperature Change in Output Voltage Voltage VREF_MAX VREF_MIN Temperature Range Figure 48. VREF vs Temperature Profile Temperature coefficient may be expressed analytically as Equation 3: TD = (VREF_MAX - VREF_MIN) VREF x ΔT x 106 ppm where • • • • • • TD = Temperature drift VREF = Nominal preset output voltage VREF_MIN = Minimum output voltage over operating temperature range VREF_MAX = Maximum output voltage over operating temperature range ΔT = Operating temperature range The LM4132 features a low temperature drift of 10 ppm (maximum) to 30 ppm (maximum), depending on the grade. (3) 8.2.1.2.4 Long-Term Stability Long-term stability refers to the fluctuation in output voltage over a long period of time (1000 hours). The LM4132 features a typical long-term stability of 50 ppm over 1000 hours. The measurements are made using 5 units of each voltage option, at a nominal input voltage (5 V), with no load, at room temperature.

The center of a PCB generally has the highest mechanical and thermal expansion stress. Mounting the device near the edges or the corners of the board where mechanical stress is at its minimum. References in SOT-23 packages are generally less prone to assembly stress than devices in small outline (SOIC) packages. A mechanical isolation of the device by creating an island by cutting a U shape slot (U - SLOT) on the PCB while mounting the device helps in reducing the impact of the PCB stresses on the output voltage of the reference. This approach would also provide some thermal isolation from the rest of the circuit. Figure 54 shows a recommended printed board layout for LM4132 along with an in-set diagram, which exhibits a slot cut on three sides of the reference device. Bypass capacitors must be mounted close to the device. Mounting bypass capacitors close to the device reduces the parasitic trace components, thereby improving performance. 10.2 Layout Example PCB Top View VIN VREF PCB Length LM4132 PCB Side View STRESS U - SLOT N/C GND STRESS EN U - SLOT VREF LM4132 N/C PCB Length GND Set CIN close to VIN and GND EN N/C COUT LM4132 CIN Set COUT close to VOUT and GND VREF VIN Figure 54.
