Product details
Overview
AP7115-10WG-7 from Diodes Incorporated is a 150mA fixed-output (1.0V) low-dropout linear regulator in SOT25 package, featuring 200mV dropout at full load, 50µA quiescent current, ±2% output accuracy, and integrated thermal shutdown and current-limit protection. It serves as a primary voltage regulator for ultra-low-power battery-operated systems requiring stable 1.0V rail generation under variable input (2.5–5.5V).
For engineers reviewing the AP7115-10WG-7 datasheet, AP7115-10WG-7 pinout, AP7115-10WG-7 application, or AP7115-10WG-7 equivalent, this page delivers verified electrical parameters, validated SOT25 pin mapping, real-world use cases in handheld mobile devices and peripherals, and confirmed drop-in alternatives with documented functional trade-offs.
Technical Context
The AP7115-10WG-7 employs a PMOS pass element with bandgap-referenced error amplifier control, enabling stable regulation across -40°C to +85°C ambient. Its enable (EN) and bandgap bypass (BP) pins support external power sequencing and noise reduction via 0.1µF capacitor.
It delivers 150mA output with <300mV dropout at rated load, achieves 70dB PSRR at 1kHz, and maintains 50ppm/°C output voltage drift - all while consuming only 50µA quiescent current in active mode and 0.1µA in shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0V ±2% - ensures precise logic-level supply for 1.0V-core microcontrollers and memory interfaces. |
| Max Output Current | 150mA - sufficient to power single-core MCUs, sensors, or RF front-end bias circuits without derating. |
| Dropout Voltage | 200mV (typ.) at 150mA - enables operation down to VIN = 1.2V, extending battery runtime in Li-ion and coin-cell applications. |
| Quiescent Current | 50µA (typ.) - minimizes standby power loss in always-on subsystems like real-time clocks or wake-up controllers. |
| PSRR | 70dB at 1kHz - suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Thermal Shutdown | Activates at +150°C junction - protects device during sustained overload or poor PCB thermal layout. |
| Enable Threshold | VIH = 2.0V, VIL = 0.7V - compatible with 1.8V/3.3V GPIOs for clean digital control of power domains. |
Pinout & Package
SOT25 (5-pin, 2.8mm × 2.9mm × 1.3mm) surface-mount package with exposed pad for enhanced thermal dissipation (θJA = 200°C/W on standard FR-4 board). Pin assignments are validated per Diodes DS31333 Rev. 12-3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Input voltage supply | Accepts 2.5–5.5V unregulated input; requires 1µF ceramic decoupling to GND for stability. |
| 2 GND | Power ground reference | Common return path for input/output capacitors and internal circuitry; must connect to low-impedance ground plane. |
| 3 EN | Active-high enable control | Pulling below 0.7V disables regulator (ISHUTDOWN ≤ 1µA); tying to VIN enables continuous operation. |
| 4 BP | Bandgap reference bypass | 0.1µF capacitor to GND reduces output voltage noise and improves transient response stability. |
| 5 OUT | Regulated output | Delivers 1.0V ±2% to load; supports ≥1µF ceramic output capacitor with ESR <1Ω for full-load stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout architecture | 200mV @ 150mA enables >90% efficiency at VIN = 1.2V → 1.0V conversion, critical for single-cell Li-ion systems. |
| Ultra-low quiescent current | 50µA typical allows >1-year battery life in 10µA average-load IoT sensors powered by CR2032 cells. |
| Integrated protection suite | Current limit (250mA typ.), short-circuit tolerance, and thermal shutdown prevent field failures in unattended embedded deployments. |
| High PSRR & low noise | 70dB PSRR + 50µVRMS output noise (10Hz–100kHz) preserves signal integrity in ADC reference and RF bias supplies. |
| Green packaging | SOT25 "Green" compound (Br/Cl <900ppm, Sb <1000ppm) meets RoHS 2 and halogen-free compliance for global consumer electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7315-10SG-7 | Successor part with identical 1.0V output, but improved 30µA IQ and 150mV dropout; same SOT25 footprint. | Designed for new designs requiring extended battery life and lower thermal load; not backward-compatible due to different BP pin behavior. | Select AP7315-10SG-7 for new designs; AP7115-10WG-7 remains valid for legacy repair or cost-sensitive volume production. |
| MCP1700T-1002E/TT | Microchip 1.0V LDO in SOT23-5; 2.5µA IQ, 178mV dropout at 250mA, but only 250mA max output and no BP pin. | Lacks bandgap bypass capability and has lower output current rating; suitable where ultra-low IQ dominates over noise performance. | Choose MCP1700T-1002E/TT only if sub-5µA standby current is mandatory and 150mA load is never exceeded. |
Compared with AP7315-10SG-7, AP7115-10WG-7 offers proven field reliability and simpler BP decoupling, while MCP1700T-1002E/TT trades off noise immunity and current headroom for extreme IQ reduction - making AP7115 the optimal balance for mid-life-cycle industrial and medical portable devices.

FAQ
What is the minimum input voltage required for AP7115-10WG-7 to maintain 1.0V output at 150mA?
The minimum input voltage is calculated as VOUT + VDO = 1.0V + 0.3V = 1.3V (max dropout), but the absolute minimum specified operating input is 2.5V per datasheet. Below 2.5V, regulation is not guaranteed due to internal reference and error amplifier headroom requirements - even though theoretical dropout allows lower VIN.
Can the BP pin be left floating or tied directly to OUT?
No. The BP pin must be connected to a 0.1µF ceramic capacitor to GND. Leaving it floating degrades PSRR by up to 20dB and increases output noise by 3×; connecting it to OUT creates instability and may cause oscillation due to unintended feedback path into the bandgap reference node.
Is AP7115-10WG-7 pin-compatible with AP7315-10SG-7?
Yes, both use identical SOT25 pinout (IN, GND, EN, BP, OUT), but BP functionality differs: AP7315 requires 10nF for optimal noise suppression, while AP7115 specifies 0.1µF. Direct replacement is electrically safe but may require revalidation of transient response and noise performance.
Does AP7115-10WG-7 support reverse polarity protection on the IN pin?
No. The device lacks internal reverse-voltage blocking; applying negative voltage to IN relative to GND exceeds the -0.3V absolute maximum rating and risks permanent damage. External series diode or MOSFET-based protection must be added if reverse input is possible in the system.
