LD6938 series Dual low-dropout regulators, low noise, 300 mA Rev. 1 — 11 July 2013 Objective data sheet 1. Product profile 1.1 General description The LD6938 series consists of small-size dual Low DropOut regulators (LDO). Each device delivers two times 300 mA with a typical voltage drop of 240 mV at full output load. The devices offer two separate fixed nominal output voltages (VO(nom)) in the range of 1.2 V to 3.3 V. The LDO has an integrated Soft start to control the inrush current during start-up. The output mode, when disabled, can be high-ohmic 3-state or auto discharge. Optionally a delayed start-up circuit is available for the second output. The devices are available in a 6-bump Wafer-Level Chip-Scale Package (WLCSP) with a height of 0.47 mm. 1.2 Features and benefits           High Power Supply Rejection Ratio (PSRR) Low output noise Low quiescent current Extremely low standby current ( 0.1 A) Soft start circuit to limit inrush current Output current limiter with foldback circuit Overtemperature protection Delayed output circuit for second LDO (optional) Auto discharge or high-ohmic mode for output when disabled WLCSP6 with 0.4 mm pitch and package size of 1.2 mm  0.8 mm  0.47 mm 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 for each LDO  PSRR = 80 dB at 1 kHz  RMS noise Vn(o)RMS = 70 V at 10 Hz to 100 kHz  tstartup(reg)  200 s  VI = 1.7 V to 5.5 V  VO = 1.2 V to 3.3 V (fixed value)  Drop voltage Vdo = 240 mV at IO = 300 mA  Quiescent current Iq = 30 A for each LDO at IO = 0 mA LD6938 series NXP Semiconductors Dual low-dropout regulators, low noise, 300 mA 2.
