IMP2070/71, IMP2187 60mA/110mA/160mA Super Low Dropout CMOS Regulators with Battery Life Extending Shutdown Mode and Adjustable Output
●Load regulation and power supply PSRR have been optimized. Load regulation is typically 0.32% and PSRR is 53dB at 1kHz.
●A logic input controlled shutdown mode extends system battery life by reducing quiescent current to 0.2μA maximum. The shutdown mode can be initiated by a system microcontroller.
●The regulators were designed with ease of use and stability in mind. Stability is guaranteed for 0.47μF and greater load capacitors with an ESR up to 5Ω. Ceramic or tantalum capacitors can be used.
●Three devices with different guaranteed output current specifications are available: IMP2070 (60mA), IMP2071 (110mA) and IMP2187 (160mA).
