GPL6221 Series Low Noise CMOS Voltage Regulators with High Ripple Rejection and Low Power Consumption Less Than 0.1μA
GreenPower's GPL6221 series Low Noise CMOS Voltage Regulators are a group of positive voltage regulators manufactured by CMOS technologies with high ripple rejection, ultra-low noise, low power consumption, and low dropout voltage, which can prolong battery life in portable electronics. The GPL6221 series works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications. The GPL6221 series consumes less than 0.1μA in shutdown mode and has a fast turn-on time of less than 50μS. The series is very suitable for battery-powered equipment, such as RF applications and other systems requiring a quiet voltage source.

Order Information
Absolute Maximum Ratings (Ta=25℃,unless otherwise noted)
(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)All voltages concerning the network ground terminal.
Electrical Characteristics(VIN=VOUT+1V, CIN=COUT=1μF，TA=25℃, unless otherwise specified)
1) VOUT: Specified Output Voltage.
2) VOUT(E): Effective Output Voltage ( Ie. The output voltage when VIN = (VOUT +1.0V) and maintains a certain IOUT Value).
3) Vdif: The Difference Between Output Voltage And Input Voltage When Input Voltage Is Decreased Gradually Till Output Voltage Equals To 98% Of VOUT (E).
