ADP1710AUJZ-R7

Product Overview

The ADP1710AUJZ-R7 from Analog Devices Inc. is a surface-mount linear voltage regulator IC with one positive adjustable output. It provides up to 150 mA and supports an output setting from 0.8 V to 5 V, with a maximum input voltage of 5.5 V. The device uses a TSOT-23-5 package and includes an enable control for output activation. Protection functions cover over-current, over-temperature, and under-voltage lockout, while the specified junction temperature range is -40°C to 125°C. Its 50 µA quiescent current and 58 dB PSRR at 1 kHz support compact regulated supply points where input-to-output voltage margin and noise sensitivity require careful management.

Key Features

• Single positive adjustable output regulator with a 0.8 V to 5 V output range.
• 150 mA maximum output current and 0.25 V dropout at 150 mA.
• 50 µA quiescent current and 1.3 mA maximum supply current.
• 58 dB power-supply rejection ratio at 1 kHz.
• Enable control feature for output activation.
• Integrated over-current, over-temperature, and under-voltage lockout protection.
• Surface-mount TSOT-23-5 package with specified operating junction temperature range of -40°C to 125°C.

Applications

• Regulated supply rails for compact electronic assemblies requiring an adjustable low-current linear regulator.
• Controlled activation of a single output rail using the enable function.
• Noise-sensitive analog or mixed-signal board sections where 58 dB PSRR at 1 kHz is useful.
• Low-power standby or lightly loaded regulator points where 50 µA quiescent current reduces supply burden.
• Board-level power management in devices with surface-mount TSOT-23-5 placement and a 5.5 V maximum input constraint.

Design & Procurement Notes

When selecting the ADP1710AUJZ-R7, confirm that the available input voltage remains below the 5.5 V maximum and that the desired output can be set between 0.8 V and 5 V. The 0.25 V dropout specification at 150 mA should be used to verify sufficient headroom under full load, while the 150 mA output limit constrains the regulator to low-current rail roles. The enable control, over-current, over-temperature, and UVLO functions support controlled activation and fault protection, but the external circuit must still account for the -40°C to 125°C junction temperature range and the compact TSOT-23-5 surface-mount layout. For noise-sensitive rails, the 58 dB PSRR at 1 kHz should be checked against the system frequency profile rather than assumed across all bands.
