Product details
Overview
AP7383-36W5-7 from Diodes Incorporated is a fixed-output 3.6V ultra-low dropout (ULDO) linear regulator IC designed for space-constrained, battery-powered systems. It delivers up to 150mA output current with 500mV dropout at 50mA, ±1% output voltage accuracy over load/temperature, and only 1.8µA ground current at zero load - enabling multi-year operation in coin-cell or Li-ion portable devices.
For engineers reviewing the AP7383-36W5-7 datasheet, AP7383-36W5-7 pinout, AP7383-36W5-7 application, or AP7383-36W5-7 equivalent, key selection criteria include its 3.5–30V wide input range, thermal shutdown at +160°C, EN control capability in W5 package, and compatibility with 1µF ceramic output capacitors - critical for USB-powered instrumentation and low-power IoT sensor nodes.
Technical Context
The AP7383-36W5-7 integrates a precision voltage reference, error amplifier, resistor network for fixed 3.6V output, current-limit protection (150mA), and chip-enable logic. Its internal architecture supports stable regulation across –40°C to +125°C junction temperature with <±100ppm/°C output voltage drift.
It operates as a single-stage LDO with no external feedback required, featuring active current limiting that clamps output during overload while maintaining thermal shutdown at +160°C with +20°C hysteresis - ensuring robustness in variable-load embedded systems without external supervision circuitry.

Pinout & Package
SOT25-5 (W5) package: 2.8mm × 2.9mm × 1.05mm body, 5-pin surface-mount with exposed pad for thermal dissipation (θJA = 193°C/W on JEDEC High-K board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply connection; accepts 3.5–30V with internal ESD protection (250V MM) |
| 2 | GND | Analog/digital ground reference; tied to exposed thermal pad for heat sinking |
| 3 | VOUT | Regulated 3.6V output; requires ≥1µF ceramic capacitor for stability |
| 4 | EN | Active-high enable input; pulls output to high-impedance when <0.4V (0.01µA standby current) |
| 5 | NC | No-connect terminal; internally unconnected - recommended to tie to GND for PCB copper area optimization |

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 |
|---|---|---|---|
| MCP1700T-3602E/MB | 250mA rating, 170mV dropout @ 250mA, but only 6V max input | Limited to single-cell Li-ion or 5V USB; unsuitable for 12V/24V industrial inputs | Select when higher output current and lower dropout are needed within ≤6V input systems |
| TPS7A2036PDQNR | 300mA output, 130mV dropout @ 300mA, 2.5–6.0V input range, 2.5µA IQ | Narrower input range excludes direct 12V/24V use; optimized for low-noise analog rails | Prefer for noise-sensitive analog circuits where input is already pre-regulated to ≤6V |
Compared with MCP1700T-3602E/MB and TPS7A2036PDQNR, the AP7383-36W5-7 uniquely balances wide-input capability (up to 30V), ultra-low IQ (1.8µA), and SOT25 footprint - making it optimal for battery-to-bus universal regulation where input voltage varies across multiple domains.

FAQ
What is the minimum input voltage required for regulation at 3.6V output?
The AP7383-36W5-7 requires a minimum input voltage of 3.5V to maintain regulation. At 50mA load, its typical dropout is 360mV, meaning stable 3.6V output is guaranteed down to VIN = 4.0V. Below 3.5V, the device enters dropout and output tracks input minus internal losses.
Can the AP7383-36W5-7 be used with tantalum or aluminum electrolytic output capacitors?
No - the AP7383-36W5-7 is optimized for low-ESR ceramic capacitors (≥1µF). Tantalum or aluminum electrolytics exhibit higher ESR and capacitance drift, which can cause instability or overshoot during load transients. Diodes specifies ceramic-only stability per DS40699 Rev. 8-2 Section 8.2.
Is the EN pin internally pulled up or down?
The EN pin has no internal pull-up or pull-down. It is a high-impedance CMOS input requiring an external logic signal. To ensure startup, connect EN to VIN through a resistor or directly; to disable, drive EN below 0.4V. Leakage is ≤1µA, so weak pull-ups are acceptable in low-power designs.
Does the AP7383-36W5-7 support reverse polarity protection?
No - the AP7383-36W5-7 lacks integrated reverse-voltage protection. Applying negative voltage to VIN or VOUT may damage the IC. External protection (e.g., series Schottky diode on VIN or back-to-back MOSFETs) is required in systems prone to reverse connection or battery insertion errors.
