LD6805K/33H,115

LD6805 series Low-dropout regulators, high PSRR, 150 mA Rev. 2 25 June 2012 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. The devices are available with fixed output voltages between 1.2 V to 3.6 V. The LD6805K/xxH devices show a high-ohmic 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 1 1 mm DFN plastic package making them ideal for use in portable applications requiring component miniaturization. All devices are manufactured in monolithic silicon technology. 1.2 Features and benefits 150 mA output current rating 75 dB PSRR at 1 kHz Input voltage range 2.3 V to 5.5 V Fixed output voltage between 1.2 V to 3.6 V Dropout voltage 250 mV at 150 mA output rating Low quiescent current in shutdown mode (typical 0.1 A) 40 V RMS output noise voltage (typical value) at 10 Hz to 100 kHz Turn-on time 150 s LD6805K/xxH: high-ohmic (3-state) output state when disabled LD6805K/xxP: low-ohmic output state when disabled (auto discharge function) Integrated ESD protection up to 6 kV Human Body Model (HBM) DFN1010C-4 (SOT1194-1) plastic package with a size of 1 1 0.55 mm Pb-free, RoHS compliant and free of halogen and antimony (dark green compliant) 1.3 Applications Analog and digital interfaces requiring lower than standard supply voltages in mobile appliances such as smart phones, mobile phone handsets and cordless telephones. Other typical applications are digital still cameras, mobile internet devices, personal navigation devices and portable media players.
