MIC5205 150 mA Low-Noise LDO Regulator Features General Description • • • • • • • • • • • The MIC5205 is an efficient linear voltage regulator with ultra low-noise output, very low dropout voltage (typically 17 mV at light loads and 165 mV at 150 mA), and very low ground current (600 µA at 100 mA output). The MIC5205 offers better than 1% initial accuracy. Ultra-Low Noise Output High Output Voltage Accuracy Guaranteed 150 mA Output Low Quiescent Current Low Dropout Voltage Extremely Tight Load and Line Regulation Very Low Temperature Coefficient Current and Thermal Limiting Reverse-Battery Protection Zero Off-Mode Current Logic-Controlled Electronic Enable Applications • • • • • • • Cellular Telephones Laptop, Notebook, and Palmtop Computers Battery-Powered Equipment PCMCIA VCC and VPP Regulation/Switching Consumer/Personal Electronics SMPS Post-Regulator and DC/DC Modules High-Efficiency Linear Power Supplies Designed especially for hand-held, battery-powered devices, the MIC5205 includes a CMOS or TTL compatible enable/shutdown control input. When shut down, power consumption drops nearly to zero. Regulator ground current increases only slightly in dropout, further prolonging battery life. Key MIC5205 features include a reference bypass pin to improve its already excellent low-noise performance, reversed-battery protection, current limiting, and overtemperature shutdown. The MIC5205 is available in fixed and adjustable output voltage versions in a small SOT-23-5 package. For low-dropout regulators that are stable with ceramic output capacitors, see the µCap MIC5245/6/7 family.

Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range from 0.1 mA to 150 mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification. Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of the load current plus the ground pin current. Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a 150 mA load pulse at VIN = 16V for t = 10 ms.

EN is compatible with CMOS logic gates. If the enable/shutdown feature is not required, connect EN (pin 3) to IN (supply input, pin 1). See Figure 4-1. 4.2 Input Capacitor A 1 µF capacitor should be placed from IN to GND if there are more than 10 inches of wire between the input and the AC filter capacitor or if a battery is used as the input. 4.3 Reference Bypass Capacitor BYP (reference bypass) is connected to the internal voltage reference. A 470 pF capacitor (CBYP) connected from BYP to GND quiets this reference, providing a significant reduction in output noise. CBYP reduces the regulator phase margin; when using CBYP, output capacitors of 2.2 µF or greater are generally required to maintain stability. The start-up speed of the MIC5205 is inversely proportional to the size of the reference bypass capacitor. Applications requiring a slow ramp-up of output voltage should consider larger values of CBYP. Likewise, if rapid turn-on is necessary, consider omitting CBYP. If output noise is not a major concern, omit CBYP and leave BYP open. 4.4 Output Capacitor An output capacitor is required between OUT and GND to prevent oscillation. The minimum size of the output capacitor is dependent upon whether a reference bypass capacitor is used. 1.0 µF minimum is recommended when CBYP is not used (see Figure 4-2). 2.2 µF minimum is recommended when CBYP is 470 pF (see Figure 4-1). Larger values improve the regulator’s transient response. The output capacitor value may be increased without limit. The output capacitor should have an ESR (effective series resistance) of about 5Ω or less and a resonant frequency above 1 MHz. Ultra-low-ESR capacitors can cause a low amplitude oscillation on the output and/or underdamped transient response. Most tantalum or aluminum electrolytic capacitors are adequate; film types will work, but are more expensive. Because many aluminum electrolytics have electrolytes that freeze at about –30°C, solid tantalums are recommended for operation below –25°C. DS20005785C-page 10 At lower values of output current, less output capacitance is required for output stability. The capacitor can be reduced to 0.47 µF for current below 10 mA or 0.33 µF for currents below 1 mA. 4.5 No-Load Stability The MIC5205 will remain stable and in regulation with no load (other than the internal voltage divider) unlike many other voltage regulators. This is especially important in CMOS RAM keep-alive applications. 4.6 Thermal Considerations The MIC5205 is designed to provide 150 mA of continuous current in a very small package. Maximum power dissipation can be calculated based on the output current and the voltage drop across the part. To determine the maximum power dissipation of the package, use the junction-to-ambient thermal resistance of the device and the following basic equation: EQUATION 4-1:  T J  MAX  – T A  P D  MAX  = ----------------------------------- JA TJ(MAX) is the maximum junction temperature of the die, 125°C, and TA is the ambient operating temperature. θJA is layout dependent; Table 4-1 shows examples of junction-to-ambient thermal resistance for the MIC5205.

Footprint θJA Square Copper Clad θJC SOT-23-5 220°C/W 170°C/W 130°C/W (M5) The actual power dissipation of the regulator circuit can be determined using the equation: EQUATION 4-2: P D =  V IN – V OUT   I OUT + V IN  I GND Substituting PD(MAX) for PD and solving for the operating conditions that are critical to the application will give the maximum operating conditions for the  2017 - 2022 Microchip Technology Inc. and its subsidiaries MIC5205 regulator circuit. For example, when operating the MIC5205-3.3YM5 at room temperature with a minimum footprint layout, the maximum input voltage for a set output current can be determined as follows: EQUATION 4-3: 4.7 Fixed Regulator Applications Figure 4-1 includes a 470 pF capacitor for low-noise operation and shows EN (pin 3) connected to IN (pin 1) for an application where enable/shutdown is not required.

The maximum power dissipation must not be exceeded for proper operation. Using the output voltage of 3.3V and an output current of 150 mA, the maximum input voltage can be determined. From the Electrical Characteristics table, the maximum ground current for 150 mA output current is 2500 µA or 2.5 mA. FIGURE 4-1: Ultra-Low Noise Fixed Voltage Application. Figure 4-2 is an example of a low-noise configuration where CBYP is not required. COUT = 1 µF minimum.

The resistors set the output voltage based on the following equation: EQUATION 4-7: EQUATION 4-6: 950mW = V IN  152.5mA VIN(MAX) then equates out to 6.23V. Therefore, a 3.3V application at 150 mA of output current can accept a maximum input voltage of 6.2V in a SOT-23-5 package. For a full discussion of heat sinking and thermal effects on voltage regulators, refer to the Regulator Thermals section of Microchip’s Designing with Low-Dropout Voltage Regulators handbook.  2017 - 2022 Microchip Technology Inc. and its subsidiaries V OUT = 1.242V   R2 ------- + 1  R1  This equation is correct due to the configuration of the bandgap reference. The bandgap voltage is relative to the output, as seen in the block diagram. Traditional regulators normally have the reference voltage relative to ground and have a different VOUT equation. Resistor values are not critical because ADJ (adjust) has a high input impedance, but for best results use resistors of 470 kΩ or less. A capacitor from ADJ to ground provides greatly improved noise performance. DS20005785C-page 11 MIC5205 VIN MIC5205YM5 1 R1 3 2.2μF 4 470pF FIGURE 4-3: 4.9 VOUT 5 2 R2 Ultra-Low Noise.
