Analog DevicesADP7104ACPZ-1.5-R7Linear Regulators

This high input voltage LDO is ideal 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 ADP7104 is available in seven 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 ADP7104 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 ADP7104 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 500 mA of output current in a small, low-profile footprint.

Say goodbye to unstable voltages with this LDO ADP7104ACPZ-1.5-R7 linear regulator from Analog Devices. Its typical dropout voltage at current is 0.35@500mA V. It has an overall accuracy of ±0.8 %. This voltage regulation device's single output can produce a current up to 0.5 A. Use this part at voltages between 3.3 V and 20 V. With a fixed output that has a voltage of 1.5 V, this is power management at its best. By operating at a load regulation of 0.2%/A(Typ) and line regulation of 0.015%/V you can provide a constant voltage at your output. Tape and reel packaging will encase the product during shipment, ensuring safe delivery and enabling quick mounting of components. Its polarity is positive. This voltage regulation device has an operating temperature range of -40 °C to 125 °C.
