REG102NA-2.5/250

TEXAS INSTRUMENTS  REG102NA-2.5/250  固定电压稳压器, LDO, 1.8V至10V, 150mV压差, 2.5V输出, 250mA输出, SOT-23-5

The is a single channel low dropout LDO linear regulator with fixed output in 5 pin SOT-23 package. The DMOS topology of this low noise regulator provides significant improvement over previous designs including low dropout voltage and better transient performance. In addition, no output capacitor is required for stability unlike conventional low dropout regulators that are difficult to compensate and require expensive low ESR capacitors greater than 1µF. The quiescent current remains relatively constant over load variations and under dropout conditions. On-chip trimming results in high output voltage accuracy and it is maintained over temperature, line and load variations. The REG102 internal circuitry provides current limit that protects load from damage and thermal protection circuitry keeps chip from being damaged by excessive temperature.
