Product details
Overview
AP7115-10SEG-7 from Diodes Incorporated is a 150mA fixed-output (1.0V) low-dropout linear regulator in SOT353 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 power management IC for battery-powered portable electronics requiring stable, low-noise 1.0V supply under variable load and input conditions.
For engineers reviewing the AP7115-10SEG-7 datasheet, AP7115-10SEG-7 pinout, AP7115-10SEG-7 application, or AP7115-10SEG-7 equivalent, this page delivers verified electrical parameters, validated SOT353 terminal mapping, real-world use cases in handheld devices, and confirmed drop-in alternatives with documented functional trade-offs.
Technical Context
The AP7115-10SEG-7 employs a PMOS pass element with bandgap-referenced error amplifier control, enabling stable regulation across 2.5V–5.5V input range while maintaining 1.0V output. Its internal current-limit circuit caps output at 200–250mA and sustains indefinite short-circuit operation without damage.
Thermal shutdown activates at +150°C junction temperature with 30°C hysteresis, and the BP pin accepts a 0.1µF bypass capacitor to reduce output voltage noise by suppressing bandgap reference fluctuations. PSRR reaches 70dB at 1kHz under 30mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0V ±2% - ensures precise core logic or memory I/O rail compliance in low-voltage SoC subsystems. |
| Dropout Voltage | 200mV typ. at 150mA - enables regulation from 1.2V input, extending usable battery life in single-cell Li-ion or NiMH systems. |
| Quiescent Current | 50µA typ. - minimizes standby power loss in always-on sensor nodes or sleep-mode peripherals. |
| Input Voltage Range | 2.5V to 5.5V - supports direct connection to USB VBUS, 3.3V rails, or boosted battery outputs without external pre-regulation. |
| PSRR | 70dB at 1kHz - suppresses switching noise from adjacent DC/DC converters, critical for ADC reference or RF bias stability. |
| Thermal Shutdown | Activates at +150°C with 30°C hysteresis - prevents permanent damage during sustained overload or poor PCB heat sinking. |
| Current Limit | 200–250mA typ. - provides robust fault containment while allowing brief peak loads beyond 150mA nominal rating. |
Pinout & Package
SOT353 (5-pin, 2.15mm × 1.30mm × 0.90mm) surface-mount package with exposed pad not electrically connected; RoHS-compliant, halogen-free "Green" molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Voltage Input | Primary power entry point; requires ≥1µF ceramic capacitor to GND for stability and transient response. |
| 2 GND | Ground Reference | Common return path for input/output currents and internal bandgap reference; must connect to low-impedance PCB ground plane. |
| 3 EN | Enable Control | Active-high digital enable; drives high (≥2.0V) to activate regulator, low (≤0.7V) to enter 0.1µA shutdown mode. |
| 4 BP | Bandgap Bypass | Connects 0.1µF capacitor to GND to filter reference noise and improve output voltage stability over temperature. |
| 5 OUT | Voltage Output | Regulated 1.0V source; supports ≥1µF ceramic output capacitor with ESR <1Ω for load currents up to 150mA. |
Key Features
| Feature | Design Value |
|---|---|
| Low Dropout Architecture | 200mV dropout at 150mA enables operation with minimal headroom-critical for single-cell battery systems where every millivolt extends runtime. |
| Ultra-Low Quiescent Current | 50µA typical draw preserves battery capacity in long-duration sleep states, supporting >1-year operation in coin-cell-powered IoT sensors. |
| Integrated Protection Suite | Combines current limit, thermal shutdown, and short-circuit resilience-eliminates need for external fault-handling circuitry in space-constrained designs. |
| High PSRR & Low Noise | 70dB PSRR at 1kHz and 50µVRMS output noise ensure clean power delivery to noise-sensitive analog blocks like PLLs or precision ADCs. |
| Green Packaging | SOT353 package meets RoHS 2, halogen-free (<900ppm Br/Cl, <1000ppm Sb), and lead-free requirements-supports global environmental compliance without performance compromise. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7315-10SG-7 | Successor device with identical 1.0V output, lower 30µA IQ, improved 150mV dropout, and enhanced PSRR (75dB @1kHz). | Designed for new designs; replaces AP7115 where tighter dropout or lower IQ is required without layout change. | Select AP7315-10SG-7 for new projects-Diodes explicitly marks AP7115 as "Not Recommended for New Design." |
| MCP1700T-1002E/TT | Microchip 100mA LDO with 1.0V output, 175mV dropout, 2.0µA IQ, but lacks EN and BP pins; only 3-pin SOT23 package. | Lower IQ suits ultra-long-life applications, but missing enable/bypass limits noise control and power sequencing flexibility. | Choose MCP1700T-1002E/TT only when 100mA output suffices and EN/BP functionality is unnecessary. |
Compared with AP7315-10SG-7, the AP7115-10SEG-7 offers proven field reliability but higher IQ and dropout; versus MCP1700T-1002E/TT, it delivers higher current and advanced control features at the cost of higher static power and larger footprint.

FAQ
What is the maximum continuous output current of AP7115-10SEG-7?
The AP7115-10SEG-7 guarantees 150mA continuous output current under all operating conditions within its recommended input range (2.5V–5.5V) and ambient temperature (-40°C to +85°C). Its current-limit circuit activates at 200–250mA to protect against overload, allowing brief peaks beyond 150mA without damage.
Can AP7115-10SEG-7 be used without connecting the BP pin?
Yes, the BP pin may be left unconnected if ultra-low output noise is not required; however, Diodes recommends a 0.1µF ceramic capacitor from BP to GND to reduce bandgap reference noise and improve output voltage stability-especially critical in precision analog or RF applications.
Is AP7115-10SEG-7 pin-compatible with AP7315-10SG-7?
Yes-both devices share identical SOT353 pinout (IN, GND, EN, BP, OUT), identical 1.0V output, and compatible enable/shutdown logic. The AP7315-10SG-7 is a direct functional upgrade with lower quiescent current (30µA vs. 50µA) and reduced dropout (150mV vs. 200mV), per Diodes' migration guidance.
What thermal derating applies to AP7115-10SEG-7 in SOT353 package?
In SOT353, θJA is 337°C/W. At +85°C ambient, maximum allowable power dissipation is 110mW ((125°C − 85°C)/337°C/W). For example, at 3.3V input and 1.0V output delivering 150mA, power dissipation is (2.3V × 0.15A) + (3.3V × 50µA) ≈ 347mW-exceeding safe limits unless PCB copper area or airflow is enhanced.
