Description

The TPL8020U50 product is a wide input range and low

quiescent current low dropout linear voltage regulator. The

device supports an input voltage of 6 V to 24 V and

provides maximum 200-mA output current. It is stable with

a minimum 2.2-μF ceramic capacitor.

The TPL8020U50 features a high PSRR with 56 dB at

10 kHz, which can significantly reduce the voltage ripple

generated from the previous power stage.

The TPL8020U50 implements a low quiescent current with

only 4.2-µA, which makes the TPL8020U50 a good choice

for the battery-powered portable devices.

Short to ground protection, over-current protection, and

over-temperature protection can ensure the system

reliability under different server conditions.

The TPL8020U50 is a 5-V fixed output LDO with

±2% accuracy over full operating conditions. The device

provides a SOT23-5 package with guaranteed operating

temperature range from −40°C to +125°C
