Product details
Overview
AP7217C-13SPG-13 from Diodes Incorporated is a fixed-output 1.25V, 600mA CMOS low-dropout linear regulator in SOP-8L-EP package with thermal shutdown, current limiting, and enable control. It operates from 2.5V to 5.5V input, delivers ≤2000mV dropout at full load, and consumes only 40µA typical quiescent current. Used in portable audio and handheld computing power rails.
For engineers reviewing the AP7217C-13SPG-13 datasheet, AP7217C-13SPG-13 pinout, AP7217C-13SPG-13 application, or AP7217C-13SPG-13 equivalent, key selection criteria include guaranteed 600mA output under 5.5V input, ±100ppm/°C temperature coefficient, stability with 1µF ceramic output capacitors, and EN pin logic thresholds (VIH = 1.6V, VIL = 0.25V).
Technical Context
The AP7217C-13SPG-13 employs a CMOS pass transistor architecture with internal bandgap reference and error amplifier feedback loop. Its enable-controlled startup sequence allows precise power sequencing in multi-rail systems.
It integrates overcurrent protection (750mA limit), short-circuit clamping (70mA), and thermal shutdown activation at 140°C junction temperature with 30°C hysteresis. Stability is ensured across −40°C to +85°C ambient using low-ESR ceramic capacitors without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.25V ±2.5% (1.225–1.275V) at 30mA load; supports precision analog or core logic rails. |
| Max Output Current | Guaranteed ≥600mA continuous; enables single-regulator supply for SoC or FPGA I/O banks. |
| Dropout Voltage | ≤2000mV at 600mA; permits operation down to VIN = 3.25V while maintaining regulation. |
| Quiescent Current | 40µA typical; minimizes standby power loss in battery-powered devices. |
| Enable Threshold | VIH = 1.6V min, VIL = 0.25V max; compatible with 1.8V/3.3V GPIO control without level shifting. |
| Thermal Resistance | θJA = 82°C/W (SOP-8L-EP on 2oz Cu PCB); supports 1.65W max dissipation at 25°C ambient. |
| PSRR | 55dB at 1kHz; suppresses switching noise from upstream DC/DC converters. |
Pinout & Package
SOP-8L-EP (exposed pad) package with 1.27mm pitch, 4.9mm × 3.9mm body, and thermal-enhanced copper pad for improved heat dissipation in space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,3,5,6,7) | Ground reference and thermal path | Five ground pins provide low-impedance return and enhance thermal conduction to PCB copper pour. |
| VOUT (Pin 2) | Regulated output node | Delivers stable 1.25V to load; requires 1µF ceramic capacitor placed adjacent to pin for transient stability. |
| VIN (Pin 4) | Input supply connection | Accepts 2.5–5.5V; must be decoupled with ≥1µF ceramic capacitor near pin to suppress ripple and noise. |
| EN (Pin 8) | Active-high enable control | Pulls high ≥1.6V to activate regulator; pulls low ≤0.25V to enter 5µA standby mode. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout operation | 2000mV max at 600mA enables use with Li-ion batteries down to 3.25V while sustaining regulation. |
| Stability with small ceramics | Guaranteed stable with ≥1µF X5R/X7R ceramic output capacitors-no tantalum or electrolytic required. |
| Integrated protection | Combines thermal shutdown (140°C trip), current limit (750mA), and short-circuit clamp (70mA) for robust field reliability. |
| Green packaging | SOP-8L-EP with halogen-free, RoHS-compliant molding compound and lead-free finish per EU Directive 2002/95/EC. |
| Precision voltage reference | ±100ppm/°C tempco ensures <±3mV drift over −40°C to +85°C ambient-critical for ADC reference or sensor biasing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7361-12SAG-7 | 1.2V output, 600mA, SOT-25 package, higher dropout (300mV typ @ 300mA) | Smaller footprint but lower current capability and no enable pin | Select when board space is critical and enable control is unnecessary. |
| MCP1700T-1202E/TT | 1.2V output, 250mA, SOT-23-5, 4µA quiescent current, no current limit | Ultra-low IQ ideal for always-on sensors; insufficient for 600mA loads | Select only for ultra-low-power standby rails-not for main system regulation. |
Compared with AP7361-12SAG-7 and MCP1700T-1202E/TT, the AP7217C-13SPG-13 uniquely combines 600mA output, enable control, thermal/current protection, and SOP-8L-EP thermal performance-making it suitable for mid-power portable applications where reliability and headroom matter.

FAQ
What is the minimum input voltage required for AP7217C-13SPG-13 to maintain regulation at 600mA?
The AP7217C-13SPG-13 requires VIN ≥ VOUT + VDROPOUT = 1.25V + 2.0V = 3.25V to sustain 600mA output current while remaining in regulation. Below this, output voltage drops linearly with input; datasheet guarantees operation from 2.5V input only at reduced load currents.
Can AP7217C-13SPG-13 operate without an external enable signal?
Yes-when the EN pin is tied directly to VIN, the regulator remains continuously enabled. This configuration eliminates external control but forfeits power-gating capability. The EN pin draws only ±0.1µA, so direct tie-to-VIN introduces negligible additional load.
Is a heatsink required for AP7217C-13SPG-13 in standard PCB layout?
No dedicated heatsink is required if the SOP-8L-EP package is mounted per Diodes' recommended pad layout (AP02001) with thermal vias to inner/outer copper layers. At 600mA and 5.5V input, power dissipation is ~2.55W; θJA = 82°C/W yields ~210°C rise-so derating or airflow is needed above ~350mA in still air.
Does AP7217C-13SPG-13 require input and output capacitors, and what types are validated?
Yes-both input (≥1µF ceramic) and output (≥1µF X5R/X7R ceramic) capacitors are mandatory for stability and transient response. Diodes validates operation with 1µF 0603/0805 ceramics; larger values improve ripple rejection but are not required. Electrolytic or tantalum capacitors are not recommended due to ESR sensitivity.
