TPS78233DDCR Description

Short technical summary and product information.

The TPS78233DDCR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for battery-powered applications requiring ultra-low quiescent current. With an I Q of just 500 nA, this regulator is ideal for microprocessors, microcontrollers, and other power-sensitive devices.

This LDO provides a stable 3.3V output with a maximum output current of 150 mA. It features a wide input voltage range of 2.2 V to 5.5 V and a low dropout voltage of 130 mV at 150 mA. The device operates reliably across a temperature range of -40°C to 125°C.

Protection features include overcurrent, over temperature, and reverse polarity protection, ensuring device safety and longevity. The TPS78233DDCR is supplied in a SOT-23-5 Thin (TSOT-23-5) surface-mount package, making it suitable for space-constrained designs. Its CMOS logic-level compatible enable pin allows for easy control.

Key specifications include 3% accuracy over load, line, and temperature variations, and stability with a 1.0-µF ceramic capacitor. The PSRR is rated from 40dB to 15dB over the 10Hz to 1kHz frequency range.
