Designed specifically for battery-operated systems, the devices’ CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current is typically 50µA at full load (20 to 60 times lower than in bipolar regulators). The devices’ key features include ultra low noise operation (plus optional Bypass input); very low dropout voltage (typically 85mV, TC1072 and 180mV, TC1073 at full load) and fast response to step changes in load. An error output (ERROR ) is asserted when the devices are out-of-regulation (due to a low input voltage or excessive output current). ERROR can be used as a low battery warning or as a processor RESET signal (with the addition of an external RC network). Supply current is reduced to 0.5µA (max) and both VOUT and ERROR are disabled when the shutdown input is low. The devices incorporate both over-temperature and over-current protection. The TC1072 and TC1073 are stable with an output capacitor of only 1µF and have a maximum output current of 50mA, and 100mA respectively. For higher output current versions, please see the TC1185, TC1186, TC1187 (IOUT = 150mA) and TC1107, TC1108 and TC1173 (IOUT = 300mA) data sheets.

(If an adjustable version is desired, please see the TC1070/TC1071/TC1187 data sheet.) Unlike bipolar regulators, the TC1072 and TC1073’s supply current does not increase with load current. In addition, VOUT remains stable and within regulation over the entire 0mA to IOUTMAX load current range, (an important consideration in RTC and CMOS RAM battery back-up applications). Figure 3-1 shows a typical application circuit. The regulator is enabled any time the shutdown input (SHDN) is at or above VIH, and shutdown (disabled) when SHDN is at or below VIL. SHDN may be controlled by a CMOS logic gate, or I/O port of a microcontroller. If the SHDN input is not required, it should be connected directly to the input supply. While in shutdown, supply current decreases to 0.05µA (typical), VOUT falls to zero volts, and ERROR is opencircuited. ERROR OUTPUT OPERATION VOUT VTH HYSTERESIS (VH) ERROR VIH VOL 3.2 Output Capacitor FIGURE 3-1: TYPICAL APPLICATION CIRCUIT + VIN 1µF VOUT VOUT + 1µF C1 + Battery TC1072 TC1073 GND Bypass C3, 470pF A 1µF (min) capacitor from VOUT to ground is recommended. The output capacitor should have an effective series resistance greater than 0.1Ω and less than 5.0Ω, and a resonant frequency above 1MHz. A 1µF capacitor should be connected from V IN to GND if there is more than 10 inches of wire between the regulator and the AC filter capacitor, or if a battery is used as the power source. Aluminum electrolytic or tantalum capacitor types can be used. (Since many aluminum electrolytic capacitors freeze at approximately -30°C, solid tantalums are recommended for applications operating below -25°C.) When operating from sources other than batteries, supply-noise rejection and transient response can be improved by increasing the value of the input and output capacitors and employing passive filtering techniques. V+ SHDN Shutdown Control (to CMOS Logic or Tie to VIN if unused) ERROR R1 1M BATTLOW or RESET 0.2µF C2 3.3 Bypass Input C2 Required Only if ERROR is used as a Processor RESET Signal (See Text) 3.1 ERROR Open Drain Output A 470pF capacitor connected from the Bypass input to ground reduces noise present on the internal reference, which in turn significantly reduces output noise. If output noise is not a concern, this input may be left unconnected. Larger capacitor values may be used, but results in a longer time period to rated output voltage when power is initially applied. ERROR is driven low whenever VOUT falls out of regulation by more than – 5% (typical). This condition may be caused by low input voltage, output current limiting, or thermal limiting. The ERROR output voltage value (e.g. ERROR = VOL at 4.75V (typ.) for a 5.0V regulator and 2.85V (typ.) for a 3.0V regulator). ERROR output operation is shown in Figure 3-2. Note that ERROR is active when V OUT falls to VTH, and inactive when VOUT rises above VTH by VHYS. As shown in Figure 3-1, ERROR can be used as a battery low flag, or as a processor RESET signal (with the addition of timing capacitor C2). R1 x C2 should be chosen to maintain ERROR below VIH of the processor RESET input for at least 200 msec to allow time for the system to stabilize. Pull-up resistor R1 can be tied to VOUT, VIN or any other voltage less than (VIN + 0.3V). © DS21354B-page 6 2002 Microchip Technology Inc. TC1072/TC1073 4.0 4.1 THERMAL CONSIDERATIONS Thermal Shutdown Equation 4-1 can be used in conjunction with Equation 4-2 to ensure regulator thermal operation is within limits. For example: Given: VINMAX = 3.0V ±5% VOUTMIN = 2.7V – 2.5% ILOADMAX = 40mA TJMAX TAMAX = 125°C = 55°C Integrated thermal protection circuitry shuts the regulator off when die temperature exceeds 160°C. The regulator remains off until the die temperature drops to approximately 150°C. 4.2 Power Dissipation The amount of power the regulator dissipates is primarily a function of input and output voltage, and output current. The following equation is used to calculate worst case actual power dissipation: Find: 1. Actual power dissipation 2. Maximum allowable dissipation Actual power dissipation: PD ≈ (VINMAX – VOUTMIN)ILOADMAX = [(3.0 x 1.05) – (2.7 x .975)]40 x 10–3 = 20.7mW Maximum allowable power dissipation: EQUATION 4-1: PD ≈ (VINMAX – V OUTMIN)ILOADMAX Where: PD VINMAX VOUTMIN ILOAD MAX = Worst case actual power dissipation = Maximum voltage on VIN = Minimum regulator output voltage = Maximum output (load) current The maximum allowable power dissipation (Equation 4-2) is a function of the maximum ambient temperature (TAMAX), the maximum allowable die temperature (TJMAX) and the thermal resistance from junction-to-air (θJA). The 6-Pin SOT-23A package has a θJA of approximately 220°C/Watt. PDMAX = (TJMAX – TAMAX) θJA = (125 – 55) 220 = 318mW In this example, the TC1072 dissipates a maximum of 20.7mW; below the allowable limit of 318mW. In a similar manner, Equation 4-1 and Equation 4-2 can be used to calculate maximum current and/or input voltage limits. EQUATION 4-2: PDMAX= (TJMAX – TAMAX) θJA Where all terms are previously defined. 4.3 Layout Considerations The primary path of heat conduction out of the package is via the package leads. Therefore, layouts having a ground plane, wide traces at the pads, and wide power supply bus lines combine to lower θJA and therefore increase the maximum allowable power dissipation limit. 2002 Microchip Technology Inc.
