Product details
Overview
AP7354-12W5-7 from Diodes Incorporated is a 1.2V fixed-output, 150mA ultra-low quiescent current LDO regulator in SOT25 package, featuring ±1% output accuracy, 0.25µA quiescent current, and enable-controlled shutdown-designed for power management in battery-constrained wearable sensors and IoT edge nodes.
For engineers reviewing the AP7354-12W5-7 datasheet, AP7354-12W5-7 pinout, AP7354-12W5-7 application, or AP7354-12W5-7 equivalent, key selection criteria include dropout voltage at 150mA (0.60V typ), EN logic thresholds (0.4V low / 1.0V high), thermal resistance (162°C/W), and absence of integrated output discharge in this variant.
Technical Context
The AP7354-12W5-7 implements a PMOS pass transistor architecture with internal voltage reference and error amplifier, enabling stable regulation across 2.0V–5.5V input range while maintaining 1.2V output under load. Its enable input directly controls NMOS gate drive to enter sub-20nA standby mode.
It operates without external compensation, stabilized by 0.1µF ceramic input/output capacitors, and delivers load transient response within ±40mV for 1mA→150mA steps-critical for intermittent sensor wake-up cycles in energy-harvesting systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2V ±1% at +25°C; ±2% over -40°C to +85°C - ensures consistent biasing for low-voltage MCUs and analog front-ends. |
| Max Output Current | 150mA guaranteed - supports moderate-current peripherals like BLE radios or image sensor interfaces without derating. |
| Quiescent Current | 0.25µA typical - extends battery life in multi-year deployments for coin-cell-powered devices. |
| Dropout Voltage | 0.60V typical at 150mA - enables operation down to 1.8V input, compatible with single Li-ion or two alkaline cells. |
| Enable Thresholds | VEN(H) = 1.0V min, VEN(L) = 0.4V max - interoperable with 1.8V/3.3V GPIOs without level-shifting. |
| Thermal Resistance | θJA = 162°C/W (SOT25) - limits junction temperature rise to <13°C at 150mA in still air, avoiding thermal shutdown. |
| ESD Rating | HBM >4kV - withstands handling in non-ESD-controlled assembly environments. |
Pinout & Package
SOT25 package: 5-pin surface-mount plastic package with exposed pad not connected; dimensions 2.80×1.60×1.10mm (L×W×H); RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main power input; must be decoupled with ≥0.1µF ceramic capacitor placed adjacent to pin to suppress supply noise. |
| 2 | GND | Analog/digital ground reference; requires low-impedance connection to PCB ground plane to minimize PSRR degradation. |
| 3 | VOUT | Regulated 1.2V output; connects directly to load; output capacitor must be placed within 2mm of this pin and GND. |
| 4 | EN | Active-high enable; floating state is undefined - must be tied to VIN or controlled logic to prevent erratic startup/shutdown. |
| 5 | GND | Second ground terminal; electrically common with Pin 2 but provides additional current return path for improved thermal and EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ operation | 0.25µA quiescent current enables >10-year battery life in 10µA average-load applications (e.g., environmental sensors). |
| High accuracy output | ±1% initial tolerance eliminates need for post-production calibration in precision analog signal chains. |
| Wide input voltage range | 2.0V–5.5V operation supports direct connection to USB, Li-ion, or multi-cell alkaline sources without pre-regulation. |
| Robust protection suite | Integrated current limiting (60mA short-circuit), thermal shutdown, and 4kV HBM ESD rating reduce external protection components. |
| Minimal external components | Stable with 0.1µF X5R/X7R ceramics on input and output - reduces BOM count and PCB area in space-constrained wearables. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-1202E/TO | 150mA, 1.2V, 1.6µA IQ, TO-92 package - 6.4× higher quiescent current, through-hole mounting. | Used in legacy industrial controls where board rework is acceptable and footprint flexibility exists. | Select when manual assembly or socket-based prototyping is required; avoid for high-volume SMT production. |
| TPS7A0212PDBVR | 200mA, 1.2V, 25nA IQ, 2.9µA typical - lower IQ but requires 0.22µF minimum COUT, SOT-23-5 pinout differs. | Targeted at medical-grade portable diagnostics needing nanoscale leakage control and tighter load regulation. | Choose only if sub-100nA standby is mandatory; verify layout compatibility due to different pin 1 location and thermal pad requirements. |
Compared with MCP1700-1202E/TO and TPS7A0212PDBVR, the AP7354-12W5-7 offers optimal balance of ultra-low IQ (0.25µA), SMT-ready SOT25 footprint, and proven field reliability in consumer wearables-without demanding exotic capacitors or complex layout rules.

FAQ
What is the maximum allowable input voltage for AP7354-12W5-7?
The absolute maximum input voltage is 6.0V per the datasheet. Operation above 5.5V violates recommended conditions and risks permanent damage. For sustained reliability, keep VIN ≤5.5V - especially critical when powering from USB or unregulated wall adapters with ripple.
Does AP7354-12W5-7 include output discharge functionality?
No. The "-12W5-7" suffix denotes the non-discharge version. Output discharge is only available in variants marked "D" (e.g., AP7354D-12W5-7), which integrate an internal NMOS switch between VOUT and GND to rapidly drain residual charge upon shutdown.
Can AP7354-12W5-7 be used with ceramic capacitors smaller than 0.1µF?
No. The datasheet specifies 0.1µF minimum for both CIN and COUT using X5R/X7R dielectrics. Smaller values risk instability, increased output ripple, and degraded transient response - verified in load step testing up to 150mA.
Is the center pad on the SOT25 package electrically connected?
No. The center pad in the SOT25 package is unconnected and must remain floating or be left un-soldered. All grounding must occur through Pins 2 and 5 - connecting the pad to GND may cause parametric shifts or thermal measurement errors.
