Product details
Overview
ADP162AUJZ-3.1-R7 from Analog Devices is a fixed-output, ultralow quiescent current CMOS linear regulator delivering 150 mA at 3.1 V with 195 mV dropout at full load, 560 nA no-load IQ, and ±3.5% accuracy over line/load/temperature - designed for battery-powered medical sensors and portable audio subsystems.
For engineers reviewing the ADP162AUJZ-3.1-R7 datasheet, ADP162AUJZ-3.1-R7 pinout, ADP162AUJZ-3.1-R7 application, or ADP162AUJZ-3.1-R7 equivalent, key selection criteria include its 560 nA quiescent current, TSOT-5 package compatibility, absence of output discharge function, and stable operation with 1 µF ceramic capacitors.
Technical Context
The ADP162AUJZ-3.1-R7 implements a PMOS pass transistor architecture enabling low dropout (195 mV @ 150 mA) and ultralow ground current (560 nA @ 0 µA load). It operates across 2.2 V to 5.5 V input range and maintains regulation with ±3.5% total output accuracy over −40°C to +125°C junction temperature.
Unlike the ADP160, this variant omits the integrated output discharge resistor, resulting in higher output impedance during shutdown. Its enable logic requires ≥1.2 V high-level input and supports automatic startup when tied to VIN.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.1 V ±1% initial, ±3.5% over line/load/temp - ensures stable rail for 3.3 V–tolerant microcontrollers and RF front-ends. |
| Max Output Current | 150 mA - sufficient for powering single-core MCUs, BLE radios, or sensor signal chains without thermal derating on standard PCBs. |
| Quiescent Current | 560 nA @ 0 µA load - extends battery life in always-on wearable monitors by minimizing standby drain. |
| Dropout Voltage | 195 mV @ 150 mA - enables operation down to 3.295 V input while maintaining 3.1 V output, critical for Li-ion battery discharge curves. |
| PSRR | 72 dB @ 100 Hz, VOUT = 1.2 V - suppresses low-frequency supply noise from switching regulators in post-regulation stages. |
| Capacitor Support | Stable with 1 µF ±30% X7R/X5R ceramic input/output - eliminates need for larger, board-space-consuming tantalum or electrolytic caps. |
| Shutdown Current | <50 nA typical - reduces system-level leakage during deep sleep modes in portable diagnostics equipment. |
Pinout & Package
ADP162AUJZ-3.1-R7 is housed in a 5-lead TSOT package (2.9 mm × 1.6 mm × 0.8 mm), optimized for space-constrained portable designs. Pin 4 is NC (no internal connection); all other pins are electrically active and defined per Analog Devices Rev. K datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input supply rail | Accepts 2.2 V–5.5 V; requires ≥1 µF ceramic bypass to GND to ensure stability and transient response. |
| GND (Pin 2) | Power ground reference | Low-impedance return path for input/output currents; must be connected directly to PCB ground plane. |
| EN (Pin 3) | Logic-enable control | Active-high input; ≥1.2 V enables regulation, ≤0.4 V disables output; ties to VIN for automatic startup. |
| NC (Pin 4) | No internal connection | Not bonded; may be left floating or tied to GND for mechanical stability - no electrical function. |
| VOUT (Pin 5) | Regulated output | Delivers fixed 3.1 V; requires ≥1 µF ceramic bypass to GND; no internal discharge path (ADP162-specific). |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow quiescent current | 560 nA at zero load enables multi-year battery life in energy-harvesting and implantable sensor nodes. |
| No output discharge circuit | Differentiates ADP162 from ADP160; preserves external capacitor charge during shutdown - essential for systems requiring fast wake-up recovery. |
| 1 µF ceramic capacitor stability | Eliminates need for ESR-tuned capacitors, reducing BOM count and simplifying layout for high-density wearables. |
| Logic-controlled enable | EN pin allows precise power sequencing with host MCU GPIO, supporting dynamic power management in multi-rail systems. |
| Thermal & short-circuit protection | Shuts down at 150°C junction temperature with 15°C hysteresis - prevents damage during sustained overload or poor heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADP160AUJZ-3.1-R7 | Includes integrated output discharge resistor (~300–600 Ω); otherwise identical specs and pinout. | Required where output must be actively pulled to GND during shutdown (e.g., to prevent backfeeding into downstream logic). | Select ADP160AUJZ-3.1-R7 only if output discharge is mandatory; ADP162AUJZ-3.1-R7 preferred for faster wake-up and lower shutdown leakage. |
| TPL7407LDR | 7-channel high-side driver with 3.1 V LDO; 2.5 µA IQ; 200 mA max; no EN pin; different package (SOIC-16). | Used in industrial I/O modules needing multiple switched loads; not a drop-in replacement due to channel count, pinout, and control interface. | Choose TPL7407LDR only for multi-load driving applications; ADP162AUJZ-3.1-R7 remains optimal for single-rail, ultra-low-IQ portable power. |
Compared with ADP160AUJZ-3.1-R7, ADP162AUJZ-3.1-R7 trades output discharge capability for lower shutdown leakage and faster wake-up, while TPL7407LDR serves a fundamentally different multi-channel driver role - making ADP162AUJZ-3.1-R7 the sole fit for space- and energy-constrained single-rail regulation.

FAQ
What is the output voltage tolerance of ADP162AUJZ-3.1-R7 over temperature and load?
ADP162AUJZ-3.1-R7 maintains ±3.5% output voltage accuracy across −40°C to +125°C junction temperature, 0 µA to 150 mA load, and 3.6 V to 5.5 V input voltage. This includes combined effects of line regulation (±0.1%/V), load regulation (0.01%/mA), and initial ±1% tolerance - verified per Analog Devices Rev. K datasheet Table 1.
Does ADP162AUJZ-3.1-R7 include an output discharge function?
No, ADP162AUJZ-3.1-R7 does not include an integrated output discharge resistor. This distinguishes it from ADP160AUJZ-3.1-R7. When disabled, ADP162AUJZ-3.1-R7 leaves VOUT floating (discharged only by external loads), enabling faster wake-up and lower shutdown leakage - confirmed in the General Description section of the ADP160/ADP161/ADP162/ADP163 Rev. K datasheet.
What package type and dimensions does ADP162AUJZ-3.1-R7 use?
ADP162AUJZ-3.1-R7 uses a 5-lead TSOT package measuring 2.9 mm × 1.6 mm × 0.8 mm (max height), with 0.95 mm lead pitch. Pin 4 is NC. This footprint matches ADP160/ADP161 variants in the same family and is documented in Figure 4 and Outline Dimensions section of the Rev. K datasheet.
Can ADP162AUJZ-3.1-R7 operate with 1 µF ceramic capacitors?
Yes, ADP162AUJZ-3.1-R7 is explicitly characterized and guaranteed stable with 1 µF ±30% X7R or X5R ceramic input and output capacitors - a core design feature highlighted in the Features and Applications Information sections of the Rev. K datasheet. Y5V/Z5U types are not recommended.
What is the maximum input voltage rating for ADP162AUJZ-3.1-R7?
The absolute maximum input voltage for ADP162AUJZ-3.1-R7 is +6.5 V relative to GND, per Table 3 (Absolute Maximum Ratings) in the Rev. K datasheet. However, functional operation is specified only from 2.2 V to 5.5 V - exceeding 5.5 V risks permanent damage even if below 6.5 V.
