LP2985-30DBVT

LP2985-30DBVT Description

The LP2985-30DBVT from Texas Instruments is a fixed 3V output, low-dropout (LDO) linear voltage regulator designed for precision power management in space-constrained applications. With a 150mA output current capability and a wide input voltage range (up to 16V), it ensures stable voltage regulation even under varying load conditions. The device operates with a low quiescent current of 95 µA, making it ideal for battery-powered systems. Packaged in a SOT23-5 surface-mount form factor, it is optimized for compact PCB designs while delivering high PSRR (45dB at 1kHz) for noise-sensitive applications.

LP2985-30DBVT Features

• Low Dropout Voltage: 0.58V @ 150mA ensures efficient operation even with low input voltages.
• Enable Control: Features an enable pin for power-saving modes, reducing standby current.
• Robust Protection: Includes over-current, over-temperature, and short-circuit protection for enhanced reliability.
• Low Noise & High PSRR: 45dB PSRR (1kHz) minimizes output ripple, critical for RF and analog circuits.
• Wide Input Range: Supports up to 16V input, accommodating various power sources.
• Low Quiescent Current: 95 µA Iq extends battery life in portable devices.
