Description
- Product Details
- The ADP7182 is a CMOS, low dropout (LDO) linear regulator that operates from −2.7 V to −28 V and provides up to −200 mA of output current. This high input voltage LDO is ideal for regulation of high performance analog and mixed signal circuits operating from −27 V down to −1.2 V rails. Using an advanced proprietary architecture, it provides high power supply rejection and low noise, and achieves excellent line and load transient response with a small 2.2 μF ceramic output capacitor.
- The ADP7182 is available in fixed output voltage and an adjustable version that allows the output voltage to range from −1.22 V to −VIN \+ VDO via an external feedback divider.
- The following fixed output voltages are available from stock: −5 V (3 mm × 3 mm LFCSP), −1.8 V, −2.5 V, −3 V, −5 V (TSOT), −1.2 V, −1.5 V, −2.5 V, −5 V (2 mm × 2 mm LFCSP). Additional voltages are available by special order.
- The ADP7182 regulator output noise is 18 μV rms independent of the output voltage. The enable logic is capable of interfacing with positive or negative logic levels for maximum flexibility.
- The ADP7182 is available in 5-lead TSOT, 6- and 8-lead LFCSP packages for a small, low profile footprint.
- Applications
- Regulation to noise sensitive applications
- Analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuits, precision amplifiers
