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] The (absolute) maximum power dissipation depends on the junction temperature Tj. Higher power dissipation is allowed with lower
ambient temperatures. The conditions to determine the specified values are Tamb = 25 C and the use of a two layer Printed-Circuit
Board (PCB).
[2] According to IEC 61340-3-1.
[3] According to JESD22-A115C.
