TPL9053-S

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

Features

Description

The TPL9053-S series products are 500-mA high PSRR,

ultra-low noise, and low dropout linear regulators with high-

output accuracy. The TPL9053-S series products support

adjustable output voltage ranging from 0.6 V to 5.3 V with

an external resistor divider, and is stable with a 4.7-μF or

larger ceramic output capacitor.

Input Voltage Range: 1.7 V to 5.5 V

•

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-S series products have high PSRR with 89

dB at 1 kHz and 5.7-μV_RMSultra-low noise. These features

make TPL9053-S series products very suitable for noise-

sensitive applications with high noise from the previous

stage power supply, such as high-performance analog

devices, or high-definition imaging equipment. Output

shortage protection and thermal overload protection

circuits improve the reliability under heavy load conditions.
