TPL730 Series

300 mA output, High PSRR,

Low-Dropout Linear Regulator

Features

Description

 Input Voltage Range: 2.4 V to 5.5 V

 Output Voltage Options:

The TPL730 series products are high-performance

and low-dropout linear regulators. The TPL730 series

products support a maximum 300 mA output current

with low-quiescent current and high PSRR. The

TPL730 series products are stable with ceramic

output capacitors from 2.2 μF to 10 μF.

− Fixed Voltage: 1.2 V, 1.5 V, 1.8 V, 2.5 V, 2.7 V,

2.8 V, 2.9 V, 3 V, 3.3 V

− Adjustable Voltage: 0.8 V to 5 V

 High Output Accuracy:

The TPL730 series products have a high PSRR with

60 dB at 1 kHz. This feature makes TPL730 series

− ±1% Typical Under Room Temperature

− ±2% Through Operating Conditions

 Maximum Output Current: 300 mA

products

very

suitable

for

power-sensitive

applications with high noise from the previous stage

power supply. As low as 49 μA quiescent current and

only 20 nA shutdown current makes the TPL730

series products ideal choices for portable devices

with battery power supply. Current limit foldback and

thermal overload protection circuits improve reliability

under heavy load conditions.

 Low Dropout Voltage: 200 mV at 300 mA

 Low Quiescent Current and Shutdown Current

 Foldback Current Limit and Thermal Protection

 Stable with 2.2 μF Ceramic Capacitor

 Inrush Input Current Limitation During Start-up

 Thermal Shutdown Protection

The TPL730 series products provide several output

voltage version options including fixed version and

adjustable version with ±2% output voltage accuracy

over operating conditions. The TPL730 series

products are guaranteed over the junction

temperature range from –40°C to +125°C.

 Junction Temperature Range: −40°C to +125°C

 Package options: SOT23-5, SC70-5, 1×1 DFN-4

Applications

 Handheld Devices with Battery Power Supply

 POS

 Video Surveillance

 Wireless and IoT modules
