The LP38691SD-3.3/NOPB is a 3.3V fixed output low-dropout (LDO) CMOS Linear Regulator provide tight output tolerance, extremely low-dropout (LDO) voltage and excellent AC performance using ultralow equivalent series resistance (ESR) ceramic output capacitors. The use of a PMOS power transistor means that no DC base-drive current is required to bias it, thus allowing ground pin current to remain below 100µA regardless of load current, input voltage or operating temperature. The IC has an enable pin (EN) which allows an external control signal to turn the regulator output ON and OFF. The enable ON/OFF threshold has no hysteresis. The voltage signal must rise and fall cleanly and promptly, through the ON and OFF voltage thresholds. Foldback current limiting is built into the LP38691 devices which reduces the amount of output current the part can deliver as the output voltage is reduced.
