IMP2185

The IMP2185 is designed as one kind of high performance CMOS low dropout voltage regulator that offers superior dropout voltage performance and load regulation characteristics as compared to the pin compatible devices offered by TelCom Semiconductor. So this device can be used in (1)pagers; (2)cellular/ GSM/PHS phones; (3)instrumentation; (4)wireless terminals; (5)battery powered systems. Also there is a digitally controlled shutdown mode extends system battery life by reducing quiescent current to 0.2mAmaximum. The shutdown mode can be initiated by a system microcontroller.

Features of the IMP2185 are:(1)lower dropout voltage for long battery life;(2)power saving shutdown mode: 0.2A shutdown current;(3)superior load regulation: 0.32%;(4)long battery life: 38A no load ground current;(5)accurate output voltage: ± 2.5% over temperature;(6)low drift output: 40ppm/°C;(7)over-current and over-temperature protection;(8)reference bypass input for low-noise and improved PSSR;(9)compact SOT-23A-5 package.

The absolute maximum ratings of the IMP2185 can be summarized as:(1)input voltage:7 V;(2)output voltage:-0.3V to VIN+0.3V;(3)maximum voltage on any pin:-0.3V to (VIN+0.3V);(4)operating junction temperature range:-40°C < TJ < 125°C;(5)storage temperature:-65°C to 150°C;(6)power dissipation: internally limited.
