Product details
Overview
AP7383-50Y-13 from Diodes Incorporated is a fixed-output 5.0V, 150mA ultra-low dropout (ULDO) linear regulator in SOT89 package, featuring 30V max input voltage, 500mV dropout at 50mA, ±1% output accuracy, and 1.8µA quiescent current - designed for stable power delivery in USB-powered instrumentation and portable computing.
For engineers reviewing the AP7383-50Y-13 datasheet, AP7383-50Y-13 pinout, AP7383-50Y-13 application, or AP7383-50Y-13 equivalent, key selection criteria include wide-input capability (3.5–30V), thermal shutdown at +160°C, EN control support in W5 variant (not present in Y package), low-ESR ceramic capacitor compatibility, and junction-to-ambient thermal resistance of 118°C/W in SOT89.
Technical Context
The AP7383-50Y-13 implements a precision bandgap reference with error amplifier feedback to maintain ±1% output regulation across -40°C to +125°C junction temperature and 1mA–150mA load range. Its internal current-limit circuit protects against overloads up to 200mA absolute maximum.
Unlike adjustable LDOs, this fixed 5.0V version integrates resistor network trimming during wafer sort for high initial accuracy and minimal drift (±100ppm/°C). It lacks an enable pin in the SOT89 (Y) package - EN functionality is exclusive to SOT25 W5 variants per pin assignment documentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1% - eliminates external resistor divider, reduces BOM count and layout sensitivity. |
| Input Voltage Range | 3.5V to 30V - supports direct connection to unregulated 12V/24V rails or automotive battery inputs with transient margin. |
| Max Output Current | 150mA continuous - sufficient for microcontroller cores, sensors, and low-power logic without thermal derating in SOT89. |
| Dropout Voltage | 250mV (typ) @ 50mA - enables regulation down to VIN = 5.25V, critical for battery-end-of-life operation. |
| Quiescent Current | 1.8µA (typ) @ zero load - extends battery life in always-on monitoring circuits. |
| Line Regulation | 0.05%/V - ensures <±2.5mV output shift over full 3.5–30V input range, vital for ADC reference stability. |
| Thermal Shutdown | Activates at +160°C with +20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
Pinout & Package
SOT89 (Y package) is a 3-pin surface-mount power package with exposed thermal pad (pin 2), offering 118°C/W θJA on JEDEC-standard 2×2-inch board. Pin 1 = VIN, Pin 2 = GND (thermal tab), Pin 3 = VOUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply connection; accepts 3.5–30V; requires 1µF ceramic input capacitor for stability. |
| 2 | GND | Power ground and thermal interface; must be soldered to large PCB copper area for heat dissipation. |
| 3 | VOUT | Regulated 5.0V output; requires 1µF ceramic output capacitor; no EN or NC pins in this package variant. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Input Range (30V) | Enables single-regulator solution across industrial 24V, automotive 12V, and USB PD source voltages without pre-regulation. |
| Ultra-Low IQ (1.8µA) | Reduces standby power loss to <9nW per µA - critical for coin-cell or energy-harvesting applications with multi-year runtime targets. |
| Ceramic Cap Compatible | Stable with 1µF X5R/X7R MLCCs; eliminates need for larger, less reliable tantalum or aluminum electrolytics. |
| ±1% Output Accuracy | Meets tight tolerance requirements for MCU I/O supply, analog sensor biasing, and reference voltage generation without calibration. |
| Thermal Protection | Auto-recovery shutdown prevents latch-up during short-circuit events while preserving long-term reliability under intermittent overload. |
Applications
| Portable Medical Sensors | Industrial Data Loggers |

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 |
|---|---|---|---|
| MCP1703T-5002E/MB | 5.0V ±2%, 250mA, 600mV dropout @ 250mA, SOT23-5 with EN pin | Requires enable logic; higher dropout limits use below 5.6V input; smaller package but lower thermal performance (θJA = 220°C/W) | Select when board space is constrained and EN control is required; avoid in high-ambient or high-current scenarios due to thermal limitations. |
| TPS7A2050PDBVR | 5.0V ±1%, 300mA, 175mV dropout @ 300mA, 1.6µA IQ, WSON-6 with EN | Includes EN and active-low RESET; superior dropout but requires 6-pin layout and external 1µF bypass caps on both EN and IN | Choose for systems needing power-good signaling or higher current headroom; not drop-in due to pin count and enable dependency. |
Compared with MCP1703T-5002E/MB and TPS7A2050PDBVR, the AP7383-50Y-13 offers best-in-class thermal performance in SOT89 (118°C/W), widest input range (30V), and lowest cost-per-watt for 150mA applications - ideal where simplicity, ruggedness, and thermal margin outweigh need for enable or reset functions.

FAQ
Is the AP7383-50Y-13 pin-compatible with other SOT89 5V regulators like the MIC5205-5.0YM?
No. While both use SOT89, AP7383-50Y-13 has VIN–GND–VOUT pinout (1–2–3), whereas MIC5205-5.0YM uses VIN–VOUT–GND (1–2–3). Swapping them causes immediate short-circuit between VIN and VOUT. Always verify pin mapping using Diodes' DS40699 Rev. 8–2, page 3.
Does the AP7383-50Y-13 support reverse-polarity protection?
No. The device lacks integrated reverse-voltage blocking; applying negative voltage to VIN or VOUT can damage the internal PNP pass transistor. External series Schottky diode or dedicated protection IC is required for reverse-battery or hot-swap scenarios.
What is the minimum output capacitor value required for stability?
1.0µF ceramic (X5R/X7R) is the minimum specified value per DS40699 Rev. 8–2, page 2. Using <1µF risks oscillation under load transients; larger values (e.g., 2.2µF) improve PSRR above 10kHz but do not affect basic loop stability.
Can the AP7383-50Y-13 be used in automotive applications?
It is not AEC-Q100 qualified. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing - none of which apply to standard AP7383-50Y-13. Use only in non-safety-critical aftermarket or industrial-temperature-range automotive subsystems with customer validation.
