Part Name(s) : LR9203

Description : CL Capacitor-LESS 500mA Low Power CONSUMPTION HIGH SPEED LDO Regulator (Rev - 2016)

DESCRIPTION
The UTC LR9203 is a CMOS-based Low dropout Regulator with high output voltage accuracy, Low dropout, high PSRR and Low quiescent Current. The devices can provide stable output voltages even without a load Capacitor CL.
The CL Capacitor-less is possible because phase compensation is carried out internally unlike other LDOs where it is done externally. Since the output Capacitor and noise bypass Capacitor are able to be reduced, so saving the board design space.
When a CL Capacitor is used, the IC can discharge the electric charge stored at the output Capacitor through the internal switch while in standby state, and as a result the VOUT quickly returns to the VSS level.

FEATURES
* Maximum Output Current: 500mA
* Output Accuracy: ±1.0% (2.0V~5.0V), ±20mV (1.2V~1.95V)
* Output Voltage Range: 1.2V~5.0V (0.05V increments)
* Protection Current: Current Limiter (630mA TYP.), Short-circuit
   Protection, Thermal Shutdown
* Dropout Voltage: 190mV @ VOUT=2.8V, IOUT=300mA
* Low Power Consumption: 15μA (TYP.), 0.1μA (in standby)
* High PSRR: 55dB @ 1kHz, VOUT=2.8V
* Operating Ambient Temperature: -40°C~+85°C
* CL Capacitor-Less: Internal Phase Compensation

Part Name(s) : LTC4063
Linear Technology
Linear Technology
Description : Standalone Linear Li-Ion Charger with MicroPower Low Dropout Linear Regulator

DESCRIPTION
The LTC®4063 is a standalone linear charger for single cell lithium-ion batteries with an adjustable Low dropout linear Regulator (LDO). The adjustable LDO regulates an output voltage between 1.2V to 4.2V at up to 100mA load Current. When the input supply (wall adapter or USB supply) is removed, the LDO regulates the output voltage without interruption. The battery charger and LDO Regulator can be enabled individually.
No external sense resistor or external blocking diode is required for charging due to the internal MOSFET architecture. Internal thermal feedback regulates the charge Current to maintain a constant die temperature during high Power operation or high ambient temperature conditions. The float voltage is fixed at 4.2V and the charge Current is programmed with an external resistor. Charge termination methods include minimum charge Current or maximum time. With Power applied, the LTC4063 can be put into shutdown mode to reduce the supply Current to 35µA and the battery drain Current to less than 2µA.
Other features include smart recharge, undervoltage lock out, LDO Current limiting and a charge status pin to indicate when the charge cycle has completed.

■ Charge Current Programmable up to 1A
■ Integrated 100mA Adjustable Low Dropout Linear Regulator
■ Charges Single Cell Li-Ion Batteries Directly from USB Port
■ Preset Charge Voltage with ±0.35% Accuracy
