Product details
Overview
AP7217A-33SPG-13 from Diodes Incorporated is a 3.3V, 600mA CMOS low-dropout linear regulator in SOP-8L-EP package with active-low open-drain reset output (VDOUT), 50µA typical quiescent current, and 800mV dropout at full load. It operates from 3.3V to 5.5V input and delivers stable voltage for power-sensitive portable electronics including digital still cameras and handheld computers.
For engineers reviewing the AP7217A-33SPG-13 datasheet, AP7217A-33SPG-13 pinout, AP7217A-33SPG-13 application, or AP7217A-33SPG-13 equivalent, key selection criteria include guaranteed 600mA output under 5.5V input, thermal shutdown protection, stability with 1µF ceramic output capacitors, and precise 3.3V ±2% output accuracy across temperature.
Technical Context
The AP7217A-33SPG-13 integrates a bandgap reference, error amplifier, and current-limiting pass transistor in a CMOS architecture optimized for low-noise, high-PSRR regulation. Its VDOUT pin provides a reset signal with 200ms typical delay after VIN exceeds 3.23V, enabling reliable microprocessor supervision during power-up.
It features internal trimming for 3.300V ±0.066V output accuracy at 30mA, ±100ppm/°C temperature coefficient, and operates with input-to-output differential as low as 800mV at 600mA - enabling efficient operation in battery-powered systems where VIN may dip near VOUT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.300V ±0.066V at 30mA - ensures logic-level compatibility with 3.3V I/O domains without external feedback. |
| Max Output Current | 600mA minimum - supports single-rail powering of baseband processors or image sensors in compact devices. |
| Dropout Voltage | 800–900mV at 600mA - enables >3.3V operation from single-cell Li-ion (3.0–4.2V) or dual-cell alkaline sources. |
| Quiescent Current | 50µA typical - extends battery life in always-on standby modes of portable audio/video players. |
| PSRR | 55dB at 1kHz - suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Reset Delay (tRP) | 180–200ms - meets JEDEC JESD84-B42 timing requirements for NAND flash initialization and SoC boot sequencing. |
| Thermal Resistance θJA | 82°C/W (SOP-8L-EP) - allows 1.65W max power dissipation at 85°C ambient, supporting continuous 600mA load with minimal heatsinking. |
Pinout & Package
SOP-8L-EP (Exposed Pad) package with 1.27mm pitch, 4.9mm × 6.0mm footprint, and integrated thermal pad for enhanced heat transfer to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,3,5,7) | Ground reference and thermal path | Four dedicated ground pins reduce impedance and improve thermal conduction via exposed pad and multiple vias. |
| VROUT (Pin 2) | Regulated 3.3V output | Main power rail for downstream logic; stable with ≥1µF X7R/X5R ceramic capacitor. |
| VIN (Pin 4) | Input supply (3.3–5.5V) | Accepts unregulated battery or DC-DC output; requires 1µF ceramic decoupling close to pin. |
| VDOUT (Pin 6) | Open-drain reset output | Asserts low when VIN < 3.23V; pulled up externally (e.g., 100kΩ to VIN) for µP reset signaling. |
| EN (Pin 8) | Enable control (active-high) | Turns regulator on/off; threshold 1.6V (VIH), 0.25V (VIL); ties to VIN if always-on operation required. |
Key Features
| Feature | Design Value |
|---|---|
| Low ESR capacitor stability | Stable with 1µF ceramic output capacitors (X5R/X7R), eliminating need for costly tantalum or polymer types. |
| Integrated reset supervisor | Guaranteed 200ms reset pulse width ensures reliable SoC boot sequencing without external reset IC. |
| Thermal shutdown protection | Activates at 150°C junction temperature and auto-recovers after 40°C cooldown - prevents permanent damage during overload. |
| Green RoHS-compliant packaging | SOP-8L-EP with lead-free finish and halogen-free molding compound meets IPC-1752 and EU Directive 2002/95/EC. |
| Current limiting & short-circuit protection | Clamps output to ~750mA during overload and ~50mA during short circuit - protects both LDO and load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3302E/TT (Microchip) | 300mA rated, SOT-23-5, no reset output, 2.5µA IQ | Limited to ultra-low-power microcontrollers; lacks VDOUT for system reset supervision. | Select only for sub-300mA loads where quiescent current is critical and reset functionality is handled elsewhere. |
| TLS850B2TE/V1 (Infineon) | 500mA, TO-263-7, integrated watchdog, AEC-Q100 Grade 1 | Automotive-qualified with extended temp range (-40°C to +125°C); higher cost and larger footprint. | Choose for automotive infotainment modules requiring functional safety compliance; not suitable for consumer portables. |
Compared with MCP1700T-3302E/TT and TLS850B2TE/V1, the AP7217A-33SPG-13 uniquely balances 600mA output, integrated reset, SOP-8L-EP thermal performance, and consumer-grade cost - making it optimal for space-constrained, battery-powered portable electronics requiring robust power sequencing.

FAQ
What is the minimum input voltage required for regulation?
The AP7217A-33SPG-13 requires VIN ≥ VOUT + VDROPOUT. With 800mV typical dropout at 600mA, regulation is maintained down to 4.1V input. At lighter loads (e.g., 30mA), dropout drops to 350mV, allowing stable 3.3V output from as low as 3.65V input - suitable for single-cell Li-ion discharge profiles.
Can the VDOUT pin drive a microcontroller's reset input directly?
Yes - VDOUT is an open-drain output rated for 20mA sink current and compatible with standard 3.3V logic reset inputs. A 100kΩ pull-up resistor to VIN is recommended per the datasheet; no level-shifting is needed for 3.3V µPs, and the 200ms delay ensures proper deassertion timing after power stabilization.
Is the SOP-8L-EP package thermally superior to SOP-8L?
Yes - the exposed pad reduces θJA from 134°C/W (SOP-8L) to 82°C/W (SOP-8L-EP) under identical PCB layout conditions. This 39% improvement enables 1.65W max power dissipation at 85°C ambient versus 1.01W for SOP-8L, supporting sustained 600mA loads without derating in compact handheld designs.
Does the AP7217A-33SPG-13 require input/output capacitors?
Yes - a 1µF ceramic capacitor is required between VIN and GND for input decoupling, and a 1µF ceramic capacitor between VROUT and GND for output stability. The device is optimized for low-ESR ceramics (X5R/X7R); larger values improve transient response but are not mandatory for basic regulation.
