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.

1.3 Applications
Analog and digital interfaces requiring lower than standard supply voltages in mobile
appliances such as smartphones, mobile phone handsets and cordless telephones. Other
typical applications are digital still cameras, mobile internet devices, personal navigation
devices and portable media players.
