L11831A/B/C
MAXIMUM 3A, ULTRA LOW DROPOUT REGULATOR WITH ENABLE
DESCRIPTION
The UTC L11831A/B/C is a positive
voltage regulator with high performance. It has low dropout
voltage and low input
voltage, besides its output
voltage can be fixed at 1V,1.05V, 1.2V, 1.5V, 1.8V, or 2.5V depending on internal feedback resistors or ADJ (not connected to the ground) with external feedback resistors. There are two additional pin in the UTC L11831A/B/C. One is EN pin and the other is POK pin.
The UTC L11831A/B/C is specially made for applications with low input
voltage, low dropout
voltage, and low output
voltage which is almost the same as the input
voltage. Typical applications include motherboards, notebooks, set top boxes, network cards and peripheral cards.
FEATURES
* VDD
voltage 5V * Maximum 3A low-dropout
voltage regulator * High accuracy output
voltage ±1.5% * When disable VO pull low resistance * Internal over current and over temperature protection
