LP3990SD-1.5/NOPB

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

The LP3990SD-1.5/NOPB is a fixed-output linear voltage regulator providing 1.5 V at up to 150 mA. It operates with an input voltage range of 2 V to 6 V and features logic-controlled enable functionality. The device achieves 1% voltage accuracy at room temperature and maintains stability using ceramic capacitors as small as 1 µF. Quiescent current is 43 µA when enabled, dropping below 10 nA in shutdown mode. It includes thermal-overload and short-circuit protection.
