Product Overview
TPS7A03 is a Texas Instruments nanopower low-dropout regulator in the Power_Management category. The device provides 200 mA LDO source capability from a recommended 1.5 V to 6.0 V input range, with fixed output versions from 0.8 V to 5.0 V available in 50-mV steps. Recommended output current operation spans 0 mA to 200 mA, with enable operation over 0 V to 6.0 V and a maximum EN toggle frequency of 10 kHz.
Accuracy is specified over -40°C to +125°C junction temperature as ±1.5% for VOUT at or above 1.5 V and ±20 mV for VOUT below 1.5 V. At 25°C, nominal accuracy is ±1% for VOUT at or above 1.5 V under 1 µA to 1 mA load, and ±15 mV for VOUT below 1.5 V.
Package options include DQN X2SON-4 at 1.00 mm x 1.00 mm, YCH DSBGA-4 at 0.64 mm x 0.64 mm, and DBV SOT-23-5 at 2.90 mm x 1.60 mm. Recommended external capacitance includes a 1 µF input capacitor and 1 µF nominal output capacitor, with 22 µF maximum and 0.5 µF minimum effective capacitance required for stability.
