TPS70933DBVR 3.3V 150mA Low Dropout Linear Regulator IC SOT23-5

Description

TPS70933DBVR 3.3V 150mA Low Dropout Linear Regulator IC SOT23-5

Product Description

The TPS70933DBVR is a low-dropout linear regulator (LDO) from Texas Instruments. It provides a fixed 3.3 V output and can source up to 150 mA. It is designed for ultra-low quiescent current operation, making it well suited for battery-powered or always-on systems. It also includes features such as reverse-current blocking and an enable (shutdown) pin.

Key Features

• Fixed 3.3 V output

• Maximum output current: 150 mA

• Ultra-low quiescent current (≈ 1 µA)

• Input voltage range: 2.7 V to 30 V

• Dropout voltage: typically ~960 mV at 150 mA

• Output voltage accuracy: ±2 % over temperature

• Reverse-current protection (blocks current flowing from output back to input)

• Enable/shutdown pin (when disabled, output is high impedance)

• Low shutdown current (≈ 150 nA)

• Overcurrent protection and thermal shutdown

• Good power-supply rejection (PSRR) of about 80 dB (at low frequency)

• Operating temperature range: –40 °C to +125 °C

• Package: SOT-23-5

Applications

• Battery-powered and portable devices

• Always-on / standby power rails

• Microcontroller power supplies

• Sensor modules

• Wireless and IoT devices

• General low-noise, low-power voltage regulation
