Ultra-Low Quiescent Current LDO Voltage Regulator – Fixed 3.3 V low-dropout (LDO) linear voltage regulator delivering up to 150 mA output current for battery-powered devices, portable electronics, sensors, wireless modules, and embedded systems. Operates from a 2.3 V to 5.5 V input voltage and features an ultra-low 21 µA typical quiescent current, 135 mV maximum dropout voltage at 150 mA, and 60 dB PSRR at 10 kHz for efficient, low-noise power regulation. Includes an enable (EN) input, low shutdown current (<1 µA typical), overcurrent protection, thermal shutdown, and undervoltage lockout (UVLO). Optimized for use with 1 µF ceramic capacitors, operates over a −40°C to +125°C temperature range, and is housed in a 5-pin TSOT-23 package.
