R5102V

The R5102V series are designed as voltage regulators with a watchdog timer (WDT) ICs with high accuracy output voltage and low supply current by CMOS process. Each of these ICs consists of an LDO regulator, VR1 and a regulator with ultra low supply current, VR2, and a watchdog timer.

The R5102V has nine features. (1)Built-in a watchdog timer. (2)Timer period for monitoring and generating a reset signal of the watchdog timer can be set by an external capacitor. (3)Regulators can be stopped individually by /CE1 pin and /CE2 pin. (4)Low supply current. (5)The output voltage of VR1 and VR2 can be set individulally for each IC by laser trim. (6)High accuracy of output voltage +/-2.0%. (7)Time period for system monitoring and reset can be set by external capacitor. (8)Output current typ 1A and min 30mA (VR2). (9)Small package SSOP-10 (0.5mm pitch) refer to package dimensions. Those are all the main features.

Some absolute maximum ratings have been concluded into several points as follow. (1)Its input voltage would be 9V. (2)Its output voltage would be from Vss-0.3V to Vin+0.3V. (3)Its EXT output voltage would be from Vss-0.3V to Vin+0.3V. (4)Its output current 2 would be 150mA. (5)Its EXT current would be 50mA. (6)Its power dissipation would be 300mW. (7)Its operating temperature range would be from -40°C to +85°C. (8)Its storage temperature range would be from -55°C to 125°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of R5102V are concluded as follow. (1)Its input voltage would be max 8V. (2)Its supply current would be typ 30uA and max 60uA. (3)Its /CE pull-up resistance would be min 2.5Mohms and typ 5Mohms and max 10Mohms. (4)Its /CE input voltage high would be min 1.5V and max Vin. (5)Its /CE input voltage low would be min 0 and max 0.25V. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
