LD6815TD/28P NXP

LD6815 series Low dropout regulators, high PSRR, 150 mA Rev. 2 14 December 2012 Product data sheet 1. Product profile 1.1 General description Small-size Low DropOut regulator (LDO) family with ultra high Power Supply Rejection Ratio (PSRR) of 75 dB. The typical 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 nominal output voltages V between 1.2 V and 3.6 V. O(nom) The LD6815TD/xxH devices show a high-ohmic state (3-state) at the output pin when set to disabled mode. The LD6815TD/xxP devices contain a pull-down switching transistor to provide a low-ohmic output state (auto discharge function) in disabled mode. The LD6815 series devices are available in SOT753 (TSOP5) plastic package with a size of 2.9 1.5 1.0 mm. All devices are manufactured in monolithic silicon technology. 1.2 Features and benefits Overcurrent protection Auto discharge or high-ohmic output stage available Low quiescent current (0.1 A) in shutdown mode High-level ElectroStatic Discharge (ESD) protection (6 kV Human Body Model (HBM)) Industry standard TSOP5 (SOT753) package 1.3 Applications Smartphones Tablet PCs Mobile handsets Mobile internet devices Digital still cameras Portable media players 1.4 Quick reference data I = 150 mA (max) V = 2.3 V to 5.5 V OUT IN PSRR = 75 dB at 1 kHz V = 1.2 V to 3.6 V OUT RMS noise V =40mV Dropout voltage V = 250 mV n(o)RMS do at 10 Hz to 100 Hz at I =150 mA OUT t =150 s startup(reg)LD6815 series NXP Semiconductors Low dropout regulators, high PSRR, 150 mA 2.
