Product data sheet
1. Product profile
1.1 General description
The LD6805 series is a small-size Low DropOut regulator (LDO) family with ultra high
Power Supply Rejection Ratio (PSRR) of 75 dB. The voltage drop is 250 mV at 150 mA
current rating. Operating voltages can range from 2.3 V to 5.5 V. Each device has a fixed
output voltage V
O(nom)
between 1.2 V and 3.6 V.
The LD6805K/xxH devices show a high-ohmic state (3-state) at the output pin when set to
disabled mode. The LD6805K/xxP devices contain a pull-down switching transistor to
provide a low-ohmic output state (auto discharge function) in disabled mode.
The LD6805 series devices are available in a DFN1010C-4 (SOT1194-1) plastic package
with a size of 1
1
0.55 mm. The devices are ideal for use in portable applications
requiring component miniaturization.
