ADP7102 Datasheet

Linear Regulators - Standard


The ADP7102 is a CMOS, low dropout linear regulatorthat operatesfrom 3.3 V to 20 V and provides up to 300 mA of output current. This high input voltage LDO isideal for regulation of high performance analog and mixed signal circuits operating from 19 V to 1.22 V rails. Using an advanced proprietary architecture, it provides high power supply rejection, low noise, and achieves excellent line and load transient response with just a small 1 µF ceramic output capacitor.The ADP7102 is available in 7 fixed output voltage options and an adjustable version, which allows output voltages that range from 1.22 V to VIN − VDO via an external feedback divider.The ADP7102 output noise voltage is 15 μV rms and is independent of the output voltage.A digital power good output allows power system monitors to check the health of the output voltage.A user programmable precision undervoltage lockout function facilitates sequencing of multiple power supplies.The ADP7102 is available in 8-lead, 3 mm × 3 mm LFCSP and 8-lead SOIC packages. The LFCSP offers a very compact solution and also provides excellent thermal performance for applications requiring up to 300 mA of output current in a small, low-profile footprint. ADP7102 Features • Input voltage range: 3.3 V to 20 V• Maximum output current:300 mA• Low noise: 15 μV rms for fixed output versions• PSRR performance of 60 dB at 10 kHz, VOUT = 3.3 V• Reverse current protection• Low dropout voltage: 200 mV at 300 mA load• Initial accuracy: ±0.8%
