TDA8139D - STMicroelectronics

TDA8139D Double (5.1 V and adjustable) voltage regulator

PThe TDA8139 and the TDA8139/D are monolithic tedual positive voltage regulators designed to leprovide a fixed precision output voltage of 5.1 V oand an adjustable voltage between 2.8 and 16 V sfor currents up to 750 mA. bAn internal reset circuit generates a reset pulse - Owhen the voltage of OUTPUT1 drops below the )regulated voltage value. t(sFigure 1.
