FC6251 Datasheet, PDF (1/12 Pages) First Components International – 250mA Ultra-Low Droupout Positive Voltage Regulator

FC6251 250mA Ultra-Low Droupout Positive Voltage Regulator
Description
FC 6251 combines high accuracy with very low power con-
sumption, and provides high output current even when the
application requires extremely low input-output voltage dif-
ferential.
FC 6251 includes a precision voltage reference, an error
correction circuit, over-temperature protection, and a cur-
rent limited output driver. Fast transient response to load
variations provides excellent stability under dynamic load
conditions.
FC6251 comes in SOT-25 (150mW), SOT-89 (500mW)
and TO-92 packages.
Features
Maximum output current 250mA (within
maximum power dissipation)
Output voltage: from 1.8 V to 6.0V in 0.1V
increments
Output voltage ±2%
CMOS low power consumption, typically
1.0µA at V_OUT = 5.0V
Input stability typically 0.2%/ V
Ultra-low dropout voltage 0.38V @ I_OUT =
