Product details
Overview
AP7315-295W5-7 from Diodes Incorporated is a 2.95V fixed-output, 150mA low-dropout linear regulator with ±1% output voltage accuracy, 75dB PSRR at 1kHz, 60µVrms output noise (10Hz–100kHz), and 35µA quiescent current. It features enable control, operates from 1.7V to 5.25V input, and is optimized for RF supply rails in compact portable electronics.
For engineers reviewing the AP7315-295W5-7 datasheet, AP7315-295W5-7 pinout, AP7315-295W5-7 application, or AP7315-295W5-7 equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases, and validated alternative options - all grounded in Diodes' DS38352 Rev. 2-2 datasheet and official ordering information.
Technical Context
The AP7315-295W5-7 implements a CMOS-based LDO architecture with integrated voltage reference, error amplifier, and current-limit circuitry. Its fixed 2.95V output is achieved via on-die resistor network, eliminating external feedback components.
It supports active enable control (EN pin logic-high enables regulation; logic-low forces shutdown), delivers 150mA guaranteed output current, and maintains stability with ≥0.47µF ceramic input/output capacitors - critical for transient response in battery-powered RF subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.95V ±1% - ensures precise biasing for 3.0V-tolerant RF ICs without external resistive divider. |
| Max Output Current | 150mA - sufficient for powering single-band RF transceivers or camera sensor analog blocks. |
| PSRR | 75dB at 1kHz - suppresses switching noise from PMICs or DC-DC converters feeding adjacent digital circuits. |
| Output Noise | 60µVrms (10Hz–100kHz) - minimizes phase noise degradation in VCO/PLL supply paths. |
| Quiescent Current | 35µA typical - extends battery life in always-on sensor or standby RF receiver modes. |
| Dropout Voltage | 210mV at 150mA (for VOUT = 2.95V) - enables operation down to 3.16V input, compatible with single-cell Li-ion under load. |
| Input Voltage Range | 1.7V to 5.25V - supports direct connection to buck converter outputs or partially discharged batteries. |
Pinout & Package
SOT25 (5-pin) package with exposed thermal pad; footprint optimized for thermal dissipation and space-constrained PCBs. Pin 1 = VIN, Pin 2 = GND, Pin 3 = EN, Pin 4 = NC, Pin 5 = VOUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power input | Accepts 1.7–5.25V; requires local 0.47µF ceramic decoupling capacitor placed adjacent to pin. |
| GND (Pin 2) | Ground reference | Primary return path for input/output currents; must connect to low-impedance ground plane. |
| EN (Pin 3) | Enable control | Logic-compatible input: ≥1.3V enables regulation; ≤0.5V disables output and reduces IQ to 0.01µA. |
| NC (Pin 4) | No-connect | Internally unconnected; recommended to tie to GND for improved thermal conduction and EMI shielding. |
| VOUT (Pin 5) | Regulated output | Delivers stable 2.95V ±1%; requires 0.47µF ceramic capacitor placed within 2mm of pin and GND. |
Key Features
| Feature | Design Value |
|---|---|
| High PSRR (75dB @ 1kHz) | Enables clean power delivery to noise-sensitive RF front-ends without additional LC filtering. |
| Ultra-low noise (60µVrms) | Preserves signal integrity in analog signal chains such as camera ISP power domains. |
| Low quiescent current (35µA) | Supports >1-year battery life in IoT edge nodes with periodic RF wake-up cycles. |
| Thermally enhanced SOT25 | Exposed thermal pad allows PCB copper area connection to GND plane, reducing θJA by ~30°C/W vs. standard SOT23. |
| Enable-controlled shutdown | Reduces system-level standby power by cutting VOUT and limiting leakage to <1µA during sleep states. |
Applications
| RF Transceiver Power | Camera Sensor Bias |
|---|---|
|
Use Scenario: Powers 2.4GHz/5GHz Wi-Fi or Bluetooth SoC RF sections in smartphones and wearables.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2902E/TO | 2.9V fixed output, 250mA rating, 6µA IQ, but only 60dB PSRR at 1kHz and no enable pin. | Lacks EN control and lower PSRR limits suitability for RF-critical designs. | Prefer when ultra-low IQ dominates over noise/PSRR requirements and enable functionality is unused. |
| Torex XC6219B292MR-G | 2.9V output, 150mA, 35µA IQ, 70dB PSRR at 1kHz, SOT25 package, but no NC pin - 4-pin layout. | Missing NC pin reduces thermal pad area and complicates thermal relief design vs. AP7315's 5-pin SOT25. | Consider only if board re-spin accommodates different pin count and thermal pad routing. |
Compared with MCP1700-2902E/TO and XC6219B292MR-G, the AP7315-295W5-7 uniquely combines 2.95V precision, 75dB PSRR, EN control, and thermally optimized 5-pin SOT25 - making it the only choice for RF supply applications demanding simultaneous low noise, high rejection, and dynamic power gating.

FAQ
What is the minimum input voltage required for AP7315-295W5-7 to maintain regulation at full 150mA load?
The dropout voltage is 210mV maximum at 150mA and 2.95V output, so minimum input is 2.95V + 0.21V = 3.16V. Below this, output voltage drops nonlinearly per the dropout curve in Figure 7 of DS38352 Rev. 2-2, and regulation is no longer guaranteed.
Can the NC pin (Pin 4) be left floating in the SOT25 package?
No - Diodes explicitly recommends connecting Pin 4 (NC) to GND to maximize PCB copper area for thermal dissipation and improve EMI shielding. Leaving it floating degrades thermal resistance by up to 15°C/W and increases susceptibility to noise coupling.
Does AP7315-295W5-7 include internal short-circuit protection?
Yes - it features fold-back current limiting that clamps output current to approximately 55mA when VOUT is shorted to GND, preventing thermal runaway and enabling safe recovery after fault removal per Section 7.2 of the datasheet.
Is the 60µVrms output noise specification measured with specific load conditions?
Yes - the 60µVrms value is specified at IOUT = 30mA, BW = 10Hz–100kHz, CIN = COUT = 0.47µF, and TA = +25°C. Noise increases slightly at higher loads (e.g., 65µVrms at 150mA) due to increased internal current noise, as shown in Figure 11.
