Product details
Overview
AP7115-30WG-7 from Diodes Incorporated is a 150mA fixed-output (3.0V) low-dropout linear regulator in SOT25 package, featuring 200mV dropout at full load, ±2% output voltage accuracy, and 50µA quiescent current. It integrates thermal shutdown, current limit, and enable control, making it suitable for battery-powered handheld devices requiring stable low-power voltage regulation.
For engineers reviewing the AP7115-30WG-7 datasheet, AP7115-30WG-7 pinout, AP7115-30WG-7 application, or AP7115-30WG-7 equivalent, key selection criteria include dropout performance at 150mA, EN-controlled power sequencing, BP-bypass noise reduction capability, and SOT25 thermal resistance (200°C/W) for compact portable designs.
Technical Context
The AP7115-30WG-7 employs a PMOS pass element with internal bandgap reference and error amplifier to regulate output voltage. Its enable input (EN) provides active-high logic control, while the BP pin accepts a 0.1µF capacitor to suppress reference noise and improve output voltage stability.
Protection circuitry includes foldback current limiting (200–250mA typ.), thermal shutdown activation at +150°C, and short-circuit survivability. The device operates across -40°C to +85°C ambient, with line regulation of 0.02%/V and load regulation of 0.003%/mA under specified conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±2% - ensures precise rail generation for 3.3V-tolerant I/O or 3.0V microcontrollers without external feedback. |
| Dropout Voltage | 200mV max at 150mA - enables operation from single-cell Li-ion (3.0V min) or two-cell alkaline (3.0V fresh) inputs. |
| Quiescent Current | 50µA typ. - minimizes standby power loss in always-on battery systems like GSM modules or sensor nodes. |
| PSRR | 70dB at 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Thermal Shutdown | Activates at +150°C junction temperature - prevents permanent damage during sustained overload or poor PCB heatsinking. |
| Enable Threshold | VIH = 2.0V, VIL = 0.7V - compatible with 1.8V/3.3V GPIOs for controlled power-up sequencing in multi-rail systems. |
| Bandgap Bypass | 0.1µF capacitor on BP pin - reduces output voltage noise by stabilizing internal reference, critical for RF or ADC supply rails. |
Pinout & Package
SOT25 (5-pin small-outline transistor) package with exposed pad not electrically connected; thermal resistance θJA = 200°C/W on standard FR-4 board with minimum recommended copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Input voltage supply | Accepts 2.5–5.5V unregulated input; requires 1µF ceramic capacitor to GND for stability. |
| 2 GND | Power ground reference | Common return path for input/output capacitors and BP bypass; must be low-impedance connection. |
| 3 EN | Active-high enable control | Pulling below 0.7V disables regulator (ISHUTDOWN ≤ 1µA); tie to VIN if always-on operation required. |
| 4 BP | Bandgap reference bypass | 0.1µF capacitor to GND filters reference noise, directly improving output voltage noise and PSRR. |
| 5 OUT | Regulated 3.0V output | Delivers up to 150mA; stable with ≥1µF ceramic output capacitor; ESR impacts transient response stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout architecture | 200mV at 150mA enables >93% efficiency when VIN = 3.2V → VOUT = 3.0V, extending battery runtime. |
| Integrated protection | Current limit (200–250mA), thermal shutdown (+150°C), and short-circuit survival eliminate need for external fault management circuitry. |
| Ultra-low IQ | 50µA quiescent current allows >1-year standby life in coin-cell–powered IoT sensors drawing 1µA average system current. |
| High PSRR & low noise | 70dB PSRR at 1kHz plus BP-bypassable reference supports clean analog/RF supply domains in cellular handsets. |
| Green packaging | SOT25 "Green" compound: halogen-free (<900ppm Br/Cl), antimony-free (<1000ppm), fully RoHS-compliant. |

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 |
|---|---|---|---|
| AP7315-30SG-7 | Successor device with improved 120mV dropout at 150mA and 30µA IQ; same SOT25 footprint and pinout. | Designed for new designs requiring lower dropout and higher efficiency; not drop-in due to different BP pin behavior (no BP pin on AP7315). | Select AP7315-30SG-7 for new designs where reduced dropout and lower IQ justify redesigning BP bypass network. |
| MCP1700T-3002E/MB | Microchip 250mA LDO with 178mV dropout at 250mA, 1.6µA IQ, but no EN or BP pins; SOT23-5 vs SOT25 pin compatibility differs. | Lacks enable and bandgap bypass functions; suited for simpler always-on applications where lowest IQ is priority over noise control. | Choose MCP1700T-3002E/MB only if EN control and BP noise filtering are unnecessary and 1.6µA IQ outweighs missing features. |
Compared with AP7315-30SG-7, the AP7115-30WG-7 offers BP-based noise reduction essential for RF/analog rails but trades higher dropout and IQ; versus MCP1700T-3002E/MB, it provides critical enable sequencing and thermal robustness at the cost of higher quiescent current.

FAQ
What is the maximum input voltage for AP7115-30WG-7?
The absolute maximum input voltage is 5.5V. Operation above this level risks permanent damage to the internal PMOS pass transistor and bandgap reference circuit. Recommended operating range is 2.5V to 5.5V, with dropout performance optimized above 3.3V input for 3.0V output.
Can the EN pin be left floating?
No - the EN pin must not be left floating. It has no internal pull-up or pull-down. An unconnected EN pin may cause erratic startup or unintended shutdown due to noise coupling. Tie EN to VIN for always-on operation or drive with a clean logic signal referenced to the same ground.
Is a capacitor required on the BP pin?
Yes - a 0.1µF ceramic capacitor between BP and GND is required to stabilize the internal bandgap reference and reduce output voltage noise. Omitting it degrades PSRR by up to 20dB and increases RMS output noise from 50µV to >100µV in 10Hz–100kHz bandwidth.
Does AP7115-30WG-7 support reverse polarity protection?
No - the device lacks reverse-voltage protection. Applying negative voltage to IN or OUT relative to GND exceeds absolute maximum ratings (-0.3V) and may damage ESD structures. External diode or MOSFET protection must be added if reverse polarity exposure is possible in the application.
