TPS78230DDCR

The Texas Instruments TPS78230DDCR is a high-performance, low-dropout linear regulator (LDO) designed for power-sensitive applications. With an ultra-low quiescent current of 500 nA, it is ideal for battery-powered devices, microprocessors, and microcontrollers where minimizing power consumption is critical.

This LDO provides a stable 3V output voltage with an output current capability of up to 150 mA. It operates from an input voltage range of 2.2V to 5.5V, offering flexibility in power source selection. Key electrical characteristics include a low dropout voltage of 130 mV at 150 mA (typical at 25°C) and 175 mV at 150 mA (typical at 85°C), ensuring efficient power delivery. The regulator also features 3% accuracy over load, line, and temperature variations, along with protection against overcurrent and overtemperature conditions.

The TPS78230DDCR is supplied in a SOT-23-5 Thin (TSOT-23-5) surface-mount package, facilitating miniaturization and ease of integration into compact designs. It requires a 1.0-µF ceramic capacitor for stability. The device includes a CMOS logic-level-compatible enable pin for power sequencing and control.

This regulator is suitable for a wide range of applications including portable electronics, sensor modules, and embedded systems where low power consumption and reliable voltage regulation are essential. Its robust design and compact footprint make it a versatile choice for modern electronic designs.
