Product Overview
The NCP511 is an ON Semiconductor CMOS low-dropout voltage regulator for Power_Management designs requiring a fixed regulated output in a compact TSOP-5, SN suffix, Case 483 package. The regulator is specified for a nominal 150 mA output current and supports a maximum operating input voltage of 6.0 V, with an input voltage rating of 0 to 6.0 V.
Available output voltage options include 1.5 V, 1.8 V, 2.5 V, 2.7 V, 2.8 V, 3.0 V, 3.3 V, and 5.0 V, each specified at TA = 25°C and Iout = 1.0 mA. Output voltage accuracy is specified at 2.0%, with load regulation of 0.3 mV/mA typical and 0.8 mV/mA maximum over 1.0 mA to 150 mA.
Power behavior includes 40 uA typical quiescent current when enabled and 0.1 uA typical shutdown quiescent current when the enable input is 0 V. The design uses a recommended 1.0 uF input capacitor and a minimum 1.0 uF output capacitor, stable with ceramic or tantalum capacitors across ESR from a few milliohms to 3.0 ohm.
