TLV757

Texas Instruments · LDO regulator · SOT-23-5

Low-dropout linear regulator that delivers 1 A with only about 200 mV of dropout at full load, in a small SOT-23-5. A fast transient response holds the output steady under sudden load steps, an EN pin gates it, and fixed-output order codes cover the common logic rails. Internal current limit and thermal shutdown protect it. A cheap, capable point-of-load LDO for cleaning up a rail or dropping a slightly higher supply to a fixed logic voltage.

Pinout

Pin Name Type Function
1 IN power_in Input supply pin, 1.45V to 5.5V. Requires a 1µF or larger ceramic capacitor from this pin to ground (effective capacitance >0.47µF).
2 GND power_in Ground reference pin.
3 EN input Enable pin. Drive above V_HI (≥1V typ) to turn on the regulator; drive below V_LO (≤0.3V typ) to place the LDO into shutdown mode. Absolute max 6V.
4 NC unconnected No internal connection.
5 OUT power_out Regulated output voltage pin, fixed 0.6V-5.0V depending on ordering option, 1A max. Requires a 1µF-200µF ceramic capacitor (effective >0.47µF) from this pin to ground.
