Product details
Overview
AP7354-15SA-7 from Diodes Incorporated is a 1.5V fixed-output, 150mA ultra-low quiescent current LDO regulator in SOT23 package, featuring ±1% output voltage accuracy over temperature, 0.25µA quiescent current, and enable-controlled shutdown for battery-powered wearable and IoT sensor modules.
For engineers reviewing the AP7354-15SA-7 datasheet, AP7354-15SA-7 pinout, AP7354-15SA-7 application, or AP7354-15SA-7 equivalent, key selection criteria include dropout voltage at 150mA (0.43V typ), standby current (0.02µA), EN logic thresholds (0.4V low / 1.0V high), and SOT23 thermal resistance (170°C/W).
Technical Context
The AP7354-15SA-7 integrates a precision voltage reference, error amplifier, current-limit circuit, and active-high enable input-enabling precise regulation and controlled power sequencing. Its architecture supports stable operation with only 0.1µF ceramic input and output capacitors.
It delivers 1.5V output across 2.0–5.5V input range with load regulation of ±40mV (1–150mA) and line regulation of 0.02%/V. The device lacks integrated output discharge (non-D variant), requiring external discharge path if needed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±1% at +25°C; ±2% over -40°C to +85°C - ensures stable MCU core or sensor bias under thermal variation. |
| Max Output Current | 150mA - sufficient for low-power microcontrollers, BLE radios, and image sensors in compact wearables. |
| Quiescent Current | 0.25µA typ - extends battery life in always-on sensing nodes; drops to 0.02µA in shutdown mode. |
| Dropout Voltage | 0.43V typ at 150mA - enables regulation from 1.93V input, supporting single-cell Li-ion or alkaline systems. |
| Input Voltage Range | 2.0V to 5.5V - compatible with coin cells, Li-ion, USB, and multi-rail embedded supplies. |
| Enable Thresholds | VEN(H) ≥ 1.0V, VEN(L) ≤ 0.4V - interfaces directly with 1.8V/3.3V GPIO without level-shifting. |
| Thermal Resistance | θJA = 170°C/W (SOT23) - requires minimal PCB copper area for thermal management in space-constrained layouts. |
Pinout & Package
SOT23-3 package (JEDEC TO-236AB), 1.3mm × 2.4mm footprint, 0.95mm height, lead-free matte tin plating, moisture sensitivity level 1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main power input; must be decoupled with ≥0.1µF ceramic capacitor placed adjacent to pin. |
| 2 | GND | Power ground reference; connects directly to PCB ground plane to minimize noise and dropout error. |
| 3 | VOUT | Regulated 1.5V output; requires local 0.1µF ceramic capacitor and low-impedance trace to load. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 0.25µA typical enables >1-year battery life in 10µA average-current IoT sensors. |
| High output accuracy | ±1% at +25°C ensures reliable operation of 1.5V-tolerant analog peripherals and ADC references. |
| Wide input voltage range | 2.0–5.5V supports direct connection to unregulated sources like coin cells or buck converter outputs. |
| Enable control with defined thresholds | EN pin accepts standard logic levels, enabling precise system-level power sequencing without external components. |
| Robust ESD protection | 4kV HBM rating protects against handling damage during manual assembly and field operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-1502E/TO | 1.5V fixed, 250mA, 1.8µA IQ, SOT23-3 - 7× higher quiescent current than AP7354-15SA-7. | Lacks enable pin; always-on operation limits use in duty-cycled systems. | Select when higher output current is required and ultra-low IQ is not critical. |
| TPS70615DBVR | 1.5V fixed, 150mA, 0.95µA IQ, SOT23-5 - includes output discharge and thermal shutdown, but larger package and higher IQ. | EN and GND pins separated; requires 5-pin layout vs. 3-pin simplicity of AP7354-15SA-7. | Select when active output discharge is mandatory and board space permits SOT23-5. |
Compared with MCP1700-1502E/TO and TPS70615DBVR, the AP7354-15SA-7 offers the lowest quiescent current (0.25µA) in the smallest 3-pin SOT23 footprint, making it optimal for size- and battery-life-constrained designs where output discharge is unnecessary.

FAQ
What is the maximum allowable input voltage for AP7354-15SA-7?
The absolute maximum input voltage is 6.0V per the datasheet. However, recommended operating range is 2.0V to 5.5V. Exceeding 5.5V risks permanent damage even briefly, and operation above 5.5V voids reliability guarantees. Thermal derating begins above +40°C ambient.
Does AP7354-15SA-7 include output discharge functionality?
No. AP7354-15SA-7 is the non-discharge variant (standard AP7354). Output discharge is only available in AP7354D part numbers (e.g., AP7354D-15W5-7). This version relies on external discharge paths if rapid VOUT decay is required after shutdown.
Can AP7354-15SA-7 operate with ceramic capacitors smaller than 0.1µF?
No. The datasheet specifies minimum 0.1µF X5R/X7R ceramic capacitors for both input and output. Using smaller values risks instability, poor transient response, and potential oscillation-especially under load steps or temperature extremes.
Is the SOT23 package of AP7354-15SA-7 RoHS and halogen-free compliant?
Yes. AP7354-15SA-7 is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen- and antimony-free ("Green" per Diodes' definition: Br+Cl <1500ppm, Sb <1000ppm), with moisture sensitivity level 1 per J-STD-020.
