LD6915LX/1828PH

-6 LD6915 series DF N1 212 Dual low-dropout regulators, low noise, 150 mA Rev. 1 — 8 July 2013 Objective data sheet 1. Product profile 1.1 General description The LD6915 series consists of small-size dual Low DropOut regulators (LDO). Each device delivers two times 150 mA with a typical voltage drop of 120 mV at 150 mA for each LDO. The system offers two individual fixed nominal output voltages (VO(nom)) from 1.2 V to 3.6 V with high Power Supply Rejection Ratio (PSRR) of 80 dB. 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 output circuit is available for the second output. The devices are available in DFN1212-6 (SOT1229) package with a maximum height of 0.4 mm. 1.2 Features and benefits          Extremely low standby current in shutdown mode ( 0.1 A) Low quiescent current Fast turn-on time Safety features (temperature watchdog, current limiter and foldback circuit) Delayed output circuit for second LDO (optional) High PSRR Auto discharge or high-ohmic mode for output when disabled DFN1212-6 (SOT1229) with 0.4 mm pitch and package size of 1.2  1.2  0.4 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 = 150 mA for each LDO  PSRR = 80 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 V to 3.6 V (fixed value)  Dropout voltage Vdo = 120 mV at IO = 150 mA for each LDO  Quiescent current Iq = 2  35 A at IO = 0 mA LD6915 series NXP Semiconductors Dual low-dropout regulators, low noise, 150 mA 2.

TAB internal connected [1] [1] LD6915_SER Objective data sheet Pin description for DFN1212-6 (SOT1229) The TAB is GND level (it is placed on the reverse side of the IC). It is recommended to connect the TAB to GND. Leaving it unconnected is also allowed but it may result in lower thermal performance.
