... STLQ50XX50 STLQ50 1. Available upon request. November 2007 Description The STLQ50 is a BiCMOS linear regulator specifically designed for operating in environment with very low power consumption constraints. Due to the very low quiescent current (3 µA) the device is suitable for those application that have very long stand-by time allowing extension of battery life ...

... The device is stable with electrolytic and ceramic output capacitors having values higher than 1 µF (see figure typical characteristics for stability details). In the adjustable version (STLQ50) the output voltage is programmed using an external resistor divider as shown in and it can be calculated using the following formula: ...

... When considering the short circuit current take care, in any case, to not exceed the maximum power dissipation sustainable by the device. The STLQ50 features an internal thermal protection that linearly reduces the output current when the internal temperature increases, consequently given load, also the output voltage decreases. The action of the thermal protection starts at 125 ° ...
