TPL9053 Series

500-mA High PSRR, Ultra-low Noise LDO Regulator

Features

Description

◼

Input Voltage Range: 1.7 V to 5.5 V

The TPL9053 series products are 500-mA high PSRR, ultra-low

noise, low dropout linear regulators with high output accuracy.

The TPL9053 series products support adjustable output voltage

ranges from 0.6 V to 5.3 V with external resistor divider and is

stable with 4.7 μF or larger ceramic output capacitor.

Output Voltage Range: 0.6 V to 5.3 V

±1.5% Output Accuracy Over Line Regulation, Load

Regulation, and Operating Temperature Range

500 mA Maximum Output Current

◼

Low Dropout Voltage: 150 mV Typical at 500 mA

High PSRR:

The TPL9053 series products have high PSRR with 89 dB at

1kHz and 5.7 μV_RMSultra-low noise. These features make

TPL9053 series products very suitable for noise-sensitive

applications with high noise from previous stage power supply,

such as high-performance analog devices, or high-definition

imaging equipment. Output shortage protection and thermal

overload protection circuits improves the reliability under heavy

load conditions.
