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 disabled (auto discharge function) Integrated ElectroStatic Discharge (ESD) protection up to 10 kV Human Body Model (HBM)  WLCSP with 0.4 mm pitch and package size of 0.76 mm  0.76 mm  0.47 mm  Small SOT753 SMD plastic package (SOT23-5 compatible)  Pb-free, Restriction of Hazardous Substances (RoHS) compliant and free of halogen and antimony (dark green compliant) LD6836 series NXP Semiconductors Ultra low dropout regulators, low noise, 300 mA 1.3 Applications Analog and digital interfaces requiring lower than standard supply voltages in mobile appliances such as smartphones, mobile phone handsets and cordless telephones.

To minimize the effective Rth(j-a), all pins must have a solid connection to larger Cu layer areas for example to the power and ground layer. In multi-layer PCB applications, the second layer is used to create a large heat spreader area directly below the LDO. If this layer is either ground or power, it is connected with several vias to the top layer connecting to the device ground or supply. Avoid the use of solder-stop varnish under the chip. [2] Use the measurement data given for a rough estimation of the Rth(j-a) in your application. The actual Rth(j-a) value can vary in applications using different layer stacks and layouts. 8.

This means that the input voltage is below the nominal output voltage value and the pass transistor works as a plain resistor. A small dropout voltage guarantees lower power consumption and efficiency maximization.

Application information 10.1 Capacitor values The LD6836 series require external capacitors at the output to guarantee a stable regulator behavior. Do not under-run the specified minimum Equivalent Series Resistance (ESR). The absolute value of the total capacitance attached to the output pin OUT influences the shutdown time (tsd(reg)) of the LD6836 series. Also an input capacitor is recommended to keep the input voltage stable. Table 13.
