Product details
Overview
AP7362-33SP-13 from Diodes Incorporated is a fixed-output 3.3V, 1.5A ultra-low dropout linear regulator in SO-8EP package, featuring 190mV dropout at full load, ±3% output voltage accuracy over line/load/temperature, and integrated enable control with 25nA shutdown current. It delivers stable power to FPGA I/O rails and ASIC cores in routers and STBs.
For engineers reviewing the AP7362-33SP-13 datasheet, AP7362-33SP-13 pinout, AP7362-33SP-13 application, or AP7362-33SP-13 equivalent, key selection criteria include dropout voltage at 1.5A, thermal shutdown threshold (+170°C), PSRR (65dB @ 120Hz), EN logic thresholds (VIH = 1.4V, VIL = 0.65V), and SO-8EP thermal resistance (θJA = 52.8°C/W).
Technical Context
The AP7362-33SP-13 integrates a PMOS pass element with internal 0.605V reference and error amplifier for fixed 3.3V output. Its internal compensation enables stability with any capacitor type (ceramic, tantalum, aluminum) and no ESR constraints.
Enable functionality uses active-high logic with 25nA shutdown ground current and 25μs turn-on/off delay. Thermal protection activates at +170°C junction temperature with +10°C hysteresis, while current limit clamps peak output to 3.7A under short-circuit conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±3% over line, load, and temperature - ensures reliable I/O rail compliance for 3.3V logic interfaces. |
| Max Output Current | 1.5A continuous - supports high-current FPGA I/O banks and ASIC subsystems without external current boosting. |
| Dropout Voltage | 190mV typical at 1.5A - enables operation from 3.5V input when powering 3.3V loads, minimizing power loss and heat generation. |
| PSRR | 65dB @ 120Hz - suppresses low-frequency ripple from upstream SMPS stages, critical for noise-sensitive analog/digital mixed-signal systems. |
| Quiescent Current | 0.5mA typical in regulation - maintains efficiency in always-on subsystems like router management controllers. |
| Shutdown Current | 25nA - reduces standby power in battery-backed or energy-harvesting applications where microampere leakage matters. |
| Thermal Shutdown | +170°C activation with +10°C hysteresis - provides robust fault recovery during sustained overload or poor PCB heatsinking. |
Pinout & Package
AP7362-33SP-13 is housed in SO-8EP (exposed pad) package, optimized for thermal dissipation with θJA = 52.8°C/W on 2"×2" FR-4 board. The exposed pad must be externally connected to GND for optimal thermal performance and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference and primary return path for load current; connects to thermal pad for heat conduction. |
| 2 | EN | Active-high enable input; requires VIH ≥ 1.4V to activate regulator and VIL ≤ 0.65V to enter 25nA shutdown mode. |
| 3,4 | IN | Dual-input pins reduce trace inductance and IR drop; accept 2.2V–5.5V input with 6.0V absolute max rating. |
| 5,6,7 | OUT | Triple-output pins minimize voltage drop and thermal stress under 1.5A load; support low-ESR ceramic capacitors down to 2.2μF. |
| 8 | ADJ/NC | No connection (NC) in fixed-output version; unused pin electrically isolated from internal circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitor flexibility | Stable with any capacitor type (ceramic/tantalum/aluminum) and zero ESR constraints - eliminates capacitor qualification effort and BOM complexity. |
| Fast transient response | Load step recovery within microseconds (measured at 40μs/div) - maintains voltage regulation during FPGA I/O switching bursts without external compensation. |
| Low-noise regulation | 90μVrms output noise (100Hz–100kHz) - avoids need for external noise-reduction capacitors in ADC reference or RF bias supplies. |
| Robust fault protection | Integrated current limit (3.7A) and thermal shutdown (+170°C) - prevents latch-up or destruction during board-level shorts or thermal runaway. |
| Wide input range | 2.2V–5.5V operation - allows direct use of 3.3V or 5V system rails without pre-regulation, simplifying power architecture. |
Applications
| FPGA I/O Power Supply | ASIC Core Supply in Routers |

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 |
|---|---|---|---|
| MCP1826T-3302E/OT | 1.5A, 3.3V fixed, 350mV dropout @ 1.5A, 60dB PSRR @ 120Hz, SOT-23-5 package | Limited to 0.8A continuous in SOT-23-5; higher dropout increases thermal load at 1.5A | Select only for space-constrained designs where 1.5A load is intermittent and thermal margin exists. |
| TLS850F3TBV50 | 500mA, 3.3V fixed, automotive AEC-Q100 qualified, 200mV dropout @ 500mA, integrated watchdog | Current rating insufficient for 1.5A FPGA I/O; designed for automotive body electronics, not consumer STBs/routers | Use only in automotive infotainment head units requiring functional safety features, not for high-current consumer applications. |
Compared with MCP1826T-3302E/OT and TLS850F3TBV50, AP7362-33SP-13 uniquely combines 1.5A capability, 190mV dropout, and SO-8EP thermal performance-enabling single-LDO solutions for high-current digital I/O rails where alternatives require parallel devices or derating.

FAQ
What is the minimum input voltage required for AP7362-33SP-13 to maintain 3.3V output at 1.5A?
The minimum input voltage is 3.49V, calculated as VOUT + VDROPOUT = 3.3V + 0.19V. Per datasheet Section 6, dropout is guaranteed ≤240mV over temperature, so design margin requires VIN ≥ 3.54V for full 1.5A operation across -40°C to +85°C ambient.
Can AP7362-33SP-13 operate without an output capacitor?
No. Although the device is stable with any capacitor type, an output capacitor is mandatory for transient response and loop stability. Datasheet Section 8 specifies a minimum 2.2μF ceramic capacitor; omitting it causes output oscillation and failure to regulate under load steps.
Is the exposed pad (EP) of the SO-8EP package electrically connected to GND?
Yes. The exposed pad is internally connected to the die substrate and must be soldered to a PCB GND plane. Datasheet Section 3 states it is "recommended to connect it externally to GND" and serves as the primary thermal path; using it as sole GND connection risks ground bounce and thermal instability.
Does AP7362-33SP-13 require a minimum load current for regulation stability?
No. Datasheet Section 8 explicitly states "no minimum load is required to keep the device stable." The regulator remains fully regulated and stable from 0A to 1.5A output current, enabling use in standby modes where downstream logic draws negligible current.
