LD6836

LD6836 series Ultra low dropout regulators, low noise, 300 mA Rev. 2 — 5 October 2012 Product data sheet 1. Product profile 1.1 General description The LD6836 series is a small-size Low DropOut regulator (LDO) family with a typical voltage drop of 90 mV at 300 mA current rating. Operating input voltages can range from 2.3 V to 5.5 V. The devices are available with fixed output voltages between 1.2 V and 3.6 V. In disabled mode the LD6836x/xxH devices show a high-ohmic state at the output pin while the LD6836x/xxP devices contain a pull-down switching transistor to provide a low-ohmic output state (auto discharge function). The LD6836CX4 and LD6836CX4/C devices are in a 0.4 mm pitch Wafer-Level Chip-Scale Package (WLCSP) making them ideal for use in portable applications requiring component miniaturization. The LD6836TD devices are in a small SOT753 Surface-Mounted Device (SMD) plastic package. All devices are manufactured in monolithic silicon technology. 1.2 Features and benefits 300 mA output current rating Input voltage range 2.3 V to 5.5 V Fixed output voltage between 1.2 V and 3.6 V Dropout voltage 90 mV at 300 mA output rating Low quiescent current in shutdown mode (typical 0.1 A) 30 V RMS output noise voltage (typical value) at 10 Hz to 100 kHz Turn-on time 150 s 55 dB Power Supply Rejection Ratio (PSRR) at 1 kHz Over-temperature protection Output current limiter LD6836x/xxH: high-ohmic (3-state) output state when disabled LD6836x/xxP: low-ohmic output state when ...
