LD6806 series
Ultra low-dropout regulator, low noise, 200 mA
Rev. 3 — 9 December 2011
Product data sheet
1. Product profile
1.1 General description
The LD6806 series is a small-size Low-DropOut regulator (LDO) family with a typical
voltage drop of 60 mV at 200 mA current rating.
The device is available in three different surface-mounted packages, one 0.4 mm pitch
CSP, one leadless plastic package SOT886 and one gull wing package SOT753.
The operating voltage ranges from 2.3 V to 5.5 V and the output voltage ranges from
1.2 V to 3.6 V.
LD6806x/xxH devices show a high-ohmic state at the output pin, while the LD6806x/xxP
contains a pull-down switching transistor, to provide a low-ohmic output stage when the
device is disabled. All devices use the same regulator design and are manufactured in
monolithic silicon technology.
These features make the LD6806 series ideal for use in applications requiring component
miniaturization, such as mobile phone handsets, cordless telephones and personal digital
devices.

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