MIC5203-2.6BM5-TR

MIC5203 µCap 80 mA LDO Regulator Features General Description • • • • • • • • • • • The MIC5203 is a µCap 80 mA linear voltage regulator with very low dropout voltage (typically 20 mV at light loads and 300 mV at 80 mA) and very low ground current (225 µA at 20 mA output), offering better than 3% initial accuracy with a logic-compatible enable input. Tiny 4- and 5-Lead Surface-Mount Packages Wide Selection of Output Voltages Guaranteed 80 mA Output Low Quiescent Current Low Dropout Voltage Low Temperature Coefficient Current and Thermal Limiting Reversed Input Polarity Protection Zero Off-Mode Current Logic-Controlled Shutdown Stability with Low-ESR Ceramic Capacitors Applications • • • • • • Cellular Telephones Laptop, Notebook, and Palmtop Computers Battery-Powered Equipment Barcode Scanners SMPS Post-Regulator and DC/DC Modules High-Efficiency Linear Power Supplies The µCap regulator design is optimized to work with low- value, low-cost ceramic capacitors. The outputs typically require only 0.47 µF of output capacitance for stability. Designed especially for hand-held, battery-powered devices, the MIC5203 can be controlled by a CMOS or TTL compatible logic signal. When disabled, power consumption drops nearly to zero. If on-off control is not required, the enable pin may be tied to the input for 3terminal operation. The ground current of the MIC5203 increases only slightly in dropout, further prolonging battery life. Key MIC5203 features include current limiting, overtemperature shutdown, and protection against reversed battery. The MIC5203 is available in 2.8V, 3.0V, 3.3V, 3.6V, 3.8V, 4.0V, 4.5V, 4.75V, and 5.0V fixed voltages. Other voltages are available.

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. TEMPERATURE SPECIFICATIONS (Note 1) Parameters Symbol Min. Typ. Max.

Exceeding the maximum allowable power dissipation will cause the device operating junction temperature to exceed the maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability. The maximum allowable power dissipation at any TA (ambient temperature) is PD(max) = (TJ(max) – TA)/JA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.

Logic high = enabled; logic low or open = shutdown Pin Name Description Ground 3 1 IN Supply input — 4 NC Not internally connected 4 5 OUT  2021 Microchip Technology Inc. and its subsidiaries Regulator output DS20006609A-page 9 MIC5203 4.0 APPLICATION INFORMATION 4.1 Input Capacitor A 0.1 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. 4.2 Output Capacitor Typical PNP based regulators require an output capacitor to prevent oscillation. The MIC5203 is ultra-stable, requiring only 0.47 µF of output capacitance for stability. The regulator is stable with all types of capacitors, including the tiny, low-ESR ceramic chip capacitors. The output capacitor value can be increased without limit to improve transient response. 4.3 No-Load Stability The MIC5203 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. 4.4 Enable Input The MIC5203 features nearly zero off-mode current. When EN (enable input) is held below 0.6V, all internal circuitry is powered off. Pulling EN high (over 2.0V) reenables the device and allows operation. EN draws a small amount of current, typically 15 µA. While the logic threshold is TTL/CMOS compatible, EN may be pulled as high as 20V, independent of VIN. The capacitor should have a resonant frequency above 500 kHz. Ceramic capacitors work, but some dielectrics have poor temperature coefficients, which will affect the value of the output capacitor over temperature. Tantalum capacitors are much more stable over temperature, but typically are larger and more expensive. Aluminum electrolytic capacitors will also work, but they have electrolytes that freeze at about –30°C. Tantalum or ceramic capacitors are recommended for operation below –25°C.
