AS1375-BTDT-27

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AS1375-BTDT-27 is a low-power, positive voltage regulator delivering up to 200mA with a typical quiescent current of 1µA. It provides a fixed output voltage of 2.7V and accepts an input voltage range from 2V to 5.5V. The device features a very low dropout voltage of 120mV at full load and maintains strict output voltage regulation tolerances of ±1%. Integrated protections include short-circuit, overcurrent, thermal shutdown at 160°C, and under-voltage lockout. It operates within a temperature range of -40°C to +85°C and is housed in a compact 6-pin TDFN 2x2mm package.
