Product details
Overview
AP7115-30SEG-7 from Diodes Incorporated is a 150mA fixed-output (3.0V) low-dropout linear regulator in SOT353 package, featuring 200mV dropout at full load, ±2% output voltage accuracy, and 50µA quiescent current. It integrates current-limit, thermal shutdown, and enable control for battery-powered wireless handsets and portable peripherals.
For engineers reviewing the AP7115-30SEG-7 datasheet, AP7115-30SEG-7 pinout, AP7115-30SEG-7 application, or AP7115-30SEG-7 equivalent, key selection criteria include dropout performance at 150mA, EN-controlled shutdown behavior, BP bypass capacitor requirements, and thermal derating in SOT353 layout.
Technical Context
The AP7115-30SEG-7 uses a PMOS pass element with bandgap reference and error amplifier feedback to regulate 3.0V output across 2.5–5.5V input. Its internal current-limit circuit clamps output at 200–250mA and enables indefinite short-circuit survival without damage.
Thermal shutdown activates at +150°C junction temperature with 30°C hysteresis, and the BP pin accepts a 0.1µF ceramic capacitor to reduce output noise by stabilizing the bandgap reference node.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±2% over -40°C to +85°C ambient and 1–150mA load |
| Dropout Voltage | 200mV typical at 150mA - enables regulation from 3.2V input in 3.0V systems |
| Quiescent Current | 50µA typical at zero load - extends battery life in always-on standby modes |
| EN Pin Threshold | VIH = 2.0V min, VIL = 0.7V max - compatible with 1.8V/3.3V logic without level shift |
| PSRR | 70dB at 1kHz - suppresses ripple from noisy DC-DC converter inputs |
| Thermal Shutdown | Activates at +150°C junction, auto-recovers after 30°C cooldown - prevents permanent damage during overload |

| 3 EN | Enable control input | Active-high logic; drives high to enable regulator, low to reduce shutdown current to 0.1µA |
| 4 BP | Bandgap reference bypass | Connects 0.1µF ceramic capacitor to GND to reduce output voltage noise and improve stability |
| 5 OUT | Regulated output | Delivers up to 150mA at 3.0V; requires ≥1µF ceramic output capacitor with ESR <1Ω |
Key Features

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 |
|---|---|---|---|
| MCP1700T-3002E/MB | 300mA rated, 170mV dropout, 2.0µA IQ - higher current but lower quiescent current | Lacks EN and BP pins; no shutdown control or noise-reduction bypass capability | Choose when higher output current is required and EN/BP features are unnecessary |
| AP7315-30SAG-7 | Same manufacturer, pin-compatible SOT25 variant - identical electrical specs, different package thermal resistance (θJA = 200°C/W vs. 337°C/W) | SOT25 offers better thermal performance for continuous 150mA operation in confined PCB areas | Choose when board space allows SOT25 and thermal dissipation exceeds 250mW |
Compared with MCP1700T-3002E/MB, AP7115-30SEG-7 provides enable control and BP noise filtering at the cost of higher IQ; versus AP7315-30SAG-7, it trades thermal performance for smaller footprint in space-constrained designs.

FAQ
What is the minimum input voltage required for AP7115-30SEG-7 to maintain 3.0V output at 150mA?
The minimum input voltage is 3.2V, calculated as VOUT + VDO = 3.0V + 0.2V. At 150mA load, the device sustains regulation down to this headroom; below it, output voltage drops linearly with input. Input must remain ≥2.5V for functional enable and bias, but regulation ceases below 3.2V under full load.
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 between BP and GND. Floating BP degrades output voltage accuracy and increases noise; connecting BP to OUT creates instability and may cause oscillation due to unintended feedback path into the bandgap reference node.
How does thermal shutdown behave during sustained overload?
When junction temperature reaches +150°C, the regulator disables the pass element and holds output at 0V until temperature falls by ~30°C. Recovery is automatic with no external reset needed. During repeated cycling, average output current is limited by ambient temperature and PCB copper area, not by datasheet-rated 150mA.
Is AP7115-30SEG-7 suitable for powering RF sections like GSM PA bias rails?
Yes - its 50µVrms output noise and 70dB PSRR at 1kHz make it appropriate for RF power supply filtering. However, ensure BP bypass capacitor placement minimizes loop inductance, and use separate 1µF input/output ceramics with low-ESR construction to avoid modulation artifacts in transmit bursts.
