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. 1.2 Features and benefits Input voltage range 2.3 V to 5.5 V Output voltage range 1.2 V to 3.6 V Dropout voltage 60 mV at 200 mA output rating Low quiescent current in shutdown mode (typical 1.0 A) 30 V RMS output noise voltage (typical value) at 10 Hz to 100 kHz Turn-on time just 200 s 55 dB Power Supply Rejection Ratio (PSRR) at 1 kHz Temperature watchdog Current limiter LD6806xxxH: high-ohmic (3-state) output state when disabled LD6806xxxP: low-ohmic output state when disabled Integrated ESD protection of 10 kV Human Body Model WLCSP with 0.4 mm pitch and package size of 0.76 mm 0.76 mm 0.47 mm SOT886 leadless package 1.0 mm 1.45 mm 0.5 mm SOT753 plastic surface-mounted device Pb-free, RoHS compliant and free of Halogen and Antimony (dark green compliant)LD6806 series NXP Semiconductors Ultra low-dropout regulator, low noise, 200 mA 1.3 Applications Analog and digital interfaces requiring lower than standard supply voltage in mobile appliances such as mobile phones, media players and so on. 2.
