Analog Devices Inc. ADP7102ARDZ-1.5-R7 Voltage Regulator
The ADP7102ARDZ-1.5-R7 is a high-performance CMOS, low-dropout (LDO) linear voltage regulator that operates from 3.3V to 20V and provides up to 300mA of output current. This fixed 1.5V output regulator from Analog Devices Inc. offers an optimal solution for providing power in a wide range of applications, from RF and analog circuits to FPGA, DSP, and microprocessor power supplies.
With its low dropout voltage of only 140mV at 300mA, the ADP7102ARDZ-1.5-R7 ensures efficient operation even when the input-to-output differential is small, making it ideal for battery-powered devices where extending run-time is critical. The device is designed to maintain high power supply rejection ratio (PSRR) of 70dB up to 10kHz, which minimizes the noise and ripple from the power supply, thus preserving signal integrity in sensitive applications.
The regulator's fast transient response and short-circuit protection enhance the reliability of the end application. Additionally, the ADP7102ARDZ-1.5-R7 incorporates thermal overload protection to safeguard the device under extreme operating conditions. The low quiescent current of 9μA (typical) in shutdown mode contributes to the conservation of energy in battery-powered systems.
This voltage regulator comes in a compact 8-lead SOIC package, denoted by the suffix 'ARDZ', and is part of the R7 series. Its small footprint and surface-mount package make it suitable for space-constrained applications. The device also supports a wide range of operating temperatures, from -40°C to +125°C, allowing it to perform reliably in various environmental conditions.
