TPL5031 Series

300-mA Output, High PSRR,

Low-Dropout Linear Regulator

Features

Description

 Input Voltage Range: 1.5 V to 5.5 V

 Output Voltage Range:

The TPL5031 series products are 300-mAhigh PSRR,

low noise, and low dropout linear regulators with high

output accuracy. The TPL5031 series products

support both fixed output voltage ranges from 0.75 V

to 3.6 V and adjustable output voltage ranges from

0.75 V to 5 V with an external resistor divider. The

TPL5031 series products are stable with a 4.7 μF or

larger ceramic output capacitor.

− Fixed Output Voltage: 0.75 V to 3.6 V

− Adjustable Output Voltage: 0.75 V to 5 V



±1% Typical Output Accuracy Under Room

Temperature

 300 mA Maximum Output Current

 Low Dropout Voltage: 250 mV Typically at 300

The TPL5031 series products have high PSRR with

70 dB at 1 kHz. This feature makes TPL5031 series

products very suitable for power-ripple-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.

 High PSRR:

− 70 dB at 1 kHz

− 54 dB at 1 MHz

 Good Transient Response

 Stable with a 4.7 μF or Larger Ceramic Output

Capacitor

 Inrush Current Control During Startup

 Thermal Shutdown and Over-Current Protection

 Temperature Range: −40°C to +125°C

 Package Options:

The TPL5031 series products provide SOT23-5 and

1×1 DFN-4 packages with a guaranteed operating

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

− SOT23-5

− 1×1 DFN-4

Applications

 Portable and Battery-Powered Equipment

 Mobile Phones and Tablets

 Digital Cameras and Audio Devices Power

Supply

 Video Surveillance

 Wireless and IoT modules
