TCS2331
1.0uA Supply Current Low Dropout Linear Regulator
产品描述
The TCS2331 is a 1.0uA supply current and fast response low dropout voltage regulator which designed for applications requiring low quiescent current, low dropout voltage and high power supply ripple reje.ction It guarantees delivery of 300mA output current and supports preset output voltage versions range include 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 3.6V.
The TCS2331 features a precise ±2% output regulation over load and line variations, also the TCS2331 integrates many functions. The function of thermal shutdown and over current limit protect the device against thermal and current over-loads. Based on its low quiescent current consumption and its less than 0.1uA (typical) shutdown mode current, Besides with high power supply rejection ratio make the device holds well for low input voltages typically encountered in battery operation systems. The regulator is stable with small ceramic capacitor (typical 1.0uF).
