1 1.5V Low Power LDO Features Low power consumption Low voltage drop Low temperature coefficient Wide operating voltage (1V max.) TO-9 SOT-89 and SOT-5 package Applications Battery-powered equipment Communication equipment Audio/Video equipment General Description The HT115-1 is a three-terminal low power voltage regulator implemented in CMOS technology. It is available with a fixed output voltage at 1.5V. CMOS technology ensures low voltage drop and low quiescent current. Although designed primarily as a fixed voltage regulator this device can be used with external components to obtain variable voltages and currents.
