LD6835K

SOT1194-1 LD6835 series Low-dropout regulator, high PSRR, 300 mA Rev. 2 — 20 September 2013 Product data sheet 1. Product profile 1.1 General description The LD6835 series is a small-size Low-DropOut (LDO) regulator family with a high-Power Supply Rejection Ratio (PSRR) of 75 dB and a voltage drop of 240 mV at 300 mA current rating. Operating voltages range from 1.75 V to 5.5 V. The products are available with fixed nominal output voltages VO(nom) between 1.2 V and 3.6 V. The LD6835 series products are available in a DFN1010C-4 (SOT1194-1) plastic package with a size of 1 mm  1 mm  0.55 mm. The devices are ideal for use in portable applications requiring component miniaturization. 1.2 Features and benefits  High PSRR  Low quiescent current  Soft start with optimized start-up time  Temperature watchdog  Current limiter with foldback circuit  Low standby current in shutdown mode (typical 0.1 A)  Auto discharge or high-ohmic mode for the output state when disabled  DFN1010C-4 (SOT1194-1) plastic package with a size of 1 mm  1 mm  0.55 mm  Pb-free, Restriction of Hazardous Substances (RoHS) compliant, free of halogen and antimony (Dark Green compliant) 1.3 Applications  Smartphones  Mobile handsets  Digital still cameras  Tablet PCs  Mobile internet devices  Portable media players 1.4 Quick reference data  IO = 300 mA  PSRR = 75 dB at 1 kHz  RMS noise Vn(o)(RMS) = 60 V at 10 Hz to 100 kHz  tstartup(reg) = 150 s  VI = 1.75 V to 5.5 V  VO = 1.2 ...
