Product details
Overview
AP2205-15YR-13 from Diodes Incorporated is a fixed-output 1.5V ultra-low dropout (ULDO) linear regulator in SOT89R package, designed for space-constrained portable electronics requiring stable low-voltage biasing. It delivers up to 200mA output current with 100mV dropout at 100µA load, 60dB PSRR at 1kHz, ±2% output voltage accuracy, and ultra-low 36µA ground current at light load - enabling extended battery life in USB-powered devices.
For engineers reviewing the AP2205-15YR-13 datasheet, AP2205-15YR-13 pinout, AP2205-15YR-13 application, or AP2205-15YR-13 equivalent, key selection considerations include its 2.3V–24V input range, thermal shutdown and reverse-current protection, compatibility with ceramic output capacitors, and enable-controlled low-power shutdown mode.
Technical Context
The AP2205-15YR-13 integrates a precision 1.24V bandgap reference, error amplifier, and current-limit circuit within a high-voltage EPNP process. Its internal feedback network fixes VOUT at 1.5V, eliminating external resistors while maintaining ±2% initial accuracy over temperature and line/load variations.
It implements active current limiting, overtemperature shutdown, and reverse-current blocking via internal MOSFET control. The EN pin provides logic-level (2.0V high / 0.4V low) on/off control with only 3µA input current, enabling precise power sequencing in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±2% - ensures stable core/bias rail for low-voltage microcontrollers and sensors without external feedback components. |
| Input Voltage Range | 2.3V to 24V - supports direct connection to wide-input sources including automotive batteries, industrial DC rails, and multi-cell Li-ion packs. |
| Max Output Current | 200mA @ VOUT ≥ 1.8V; 150mA @ VOUT = 1.5V - matches typical load requirements of PMIC auxiliary rails and RF front-end biasing. |
| Dropout Voltage | 100mV @ IOUT = 100µA; 320mV @ IOUT = 100mA - enables regulation from 1.6V input at full load, critical for single-cell LiFePO₄ or NiMH applications. |
| PSRR | 60dB @ 1kHz - suppresses switching noise from upstream DC/DC converters, preserving signal integrity in ADC reference and analog sensor circuits. |
| Quiescent Current | 36µA @ 100µA load; 1.0µA in shutdown - minimizes standby power loss in always-on IoT nodes and battery-backed real-time clocks. |
| Thermal Shutdown | Activates at TJ ≈ +150°C - protects against sustained overload or poor PCB heatsinking in enclosed handheld enclosures. |
Pinout & Package
SOT89R is a 3-pin thermally enhanced plastic package with exposed substrate pad (pin 2), rated at θJA = 129°C/W on standard FR-4. The substrate must be connected to GND for optimal thermal performance and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply connection; accepts 2.3V–24V with transient tolerance up to 36V absolute max. |
| 2 | GND | Ground reference and thermal pad; requires low-impedance PCB copper pour for heat dissipation and noise reduction. |
| 3 | VOUT | Regulated 1.5V output; stable with ≥2.2µF ceramic capacitor and compatible with low-ESR MLCCs. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (2.3–24V) | Eliminates need for pre-regulation stages when interfacing with unregulated industrial or automotive supplies. |
| Ultra-low quiescent current (36µA) | Extends battery runtime in always-on wearables and remote sensors by reducing no-load power draw below 50µW. |
| Reverse current protection | Prevents backflow from VOUT to VIN during shutdown or input brownout - avoids unintended power coupling in multi-supply systems. |
| Enable input with 3µA leakage | Allows clean, low-power sequencing control using standard GPIOs without additional level-shifting or pull-up networks. |
| Thermal shutdown + current limit | Provides self-protecting operation under short-circuit or excessive ambient conditions without external foldback circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1502E/TT (Microchip) | 150mA max output, 600mV dropout at 250mA, no reverse-current protection | Limited to lower-current sensor biasing; unsuitable for 200mA loads or reverse-battery scenarios | Select when cost sensitivity outweighs current capability and protection features |
| Torex XC6206P152MR-G (Torex) | 150mA max, 350mV dropout at 100mA, no enable pin or thermal shutdown | Requires external enable logic and thermal derating; lacks system-level fault coverage | Choose only for simple, low-risk, low-power applications where full protection is not required |
Compared with MCP1700T-1502E/TT and XC6206P152MR-G, the AP2205-15YR-13 provides higher output current headroom, integrated reverse-current blocking, and a dedicated enable pin - making it uniquely suitable for battery-backed, safety-aware, and thermally constrained designs where reliability and feature completeness are prioritized over minimal BOM count.

FAQ
What is the minimum input voltage required for regulation at 1.5V output?
The AP2205-15YR-13 requires VIN ≥ 2.3V to operate, but stable regulation at full 1.5V output demands VIN ≥ VOUT + VDROP. With 320mV typical dropout at 100mA, minimum functional input is 1.82V - however, datasheet specifies 2.3V as absolute minimum to ensure all specifications, including accuracy and PSRR, remain valid across temperature and process variation.
Can the SOT89R package be soldered using standard reflow profiles?
Yes - the SOT89R package is rated Moisture Sensitivity Level 3 per J-STD-020 and supports standard lead-free reflow profiles. Peak temperature must not exceed +260°C for ≤10 seconds. The exposed substrate pad (pin 2) must be connected to GND and thermally anchored to ≥1 cm² of inner-layer copper for reliable thermal performance and mechanical adhesion.
Does the AP2205-15YR-13 require an external capacitor on the EN pin?
No external capacitor is required on the EN pin. It is a CMOS-compatible digital input with only 3µA leakage current and TTL/CMOS logic thresholds (VIL ≤ 0.4V, VIH ≥ 2.0V). An RC filter may be added for noise immunity in electrically noisy environments, but it is not necessary for basic enable/disable functionality.
Is the AP2205-15YR-13 qualified for automotive applications?
The AP2205-15YR-13 is not AEC-Q100 qualified. While it meets industrial temperature range (−40°C to +125°C) and includes thermal shutdown and current limiting, Diodes explicitly states that automotive-grade versions require separate qualification, PPAP capability, and IATF 16949 manufacturing - none of which apply to this standard commercial-grade part.
