Linear & Switching Voltage Regulators

LP38692MP-3.3 Description

The LP38692MP-3.3 from Texas Instruments is a high-performance, fixed-output linear voltage regulator designed to deliver a stable 3.3V output at up to 1A of continuous current. With a wide input voltage range of up to 10V, this regulator is optimized for low-dropout operation, featuring a maximum dropout voltage of 1V at 1A, making it ideal for applications where input voltage headroom is limited. The device boasts a low quiescent current of 55 µA and a high PSRR of 55dB (120Hz), ensuring efficient power management and noise suppression in sensitive circuits. Packaged in a SOT223-5 surface-mount form factor, it is suitable for space-constrained designs and is available in Tape & Reel (TR) for automated assembly.
