Product details

Overview

AP7383-30FDC-7 from Diodes Incorporated is a fixed-output 3.0V, 150mA ultra-low dropout (ULDO) linear regulator in U-DFN2020-6 (Type C) package. It operates across 3.5V–30V input range, delivers ±1% output voltage accuracy at 10mA load, features 360mV typical dropout at 50mA, and draws only 1.8µA ground current. It is designed for battery-powered instrumentation and portable USB-powered devices requiring stable low-noise supply under wide VIN variation.

For engineers reviewing the AP7383-30FDC-7 datasheet, AP7383-30FDC-7 pinout, AP7383-30FDC-7 application, or AP7383-30FDC-7 equivalent, key selection criteria include its 30V max input rating, thermal shutdown at +160°C, enable control capability, compatibility with 1µF ceramic output capacitors, and ultra-low quiescent current for extended battery life in always-on sensing nodes.

Technical Context

The AP7383-30FDC-7 integrates a precision voltage reference, error amplifier, resistor network for fixed 3.0V output, current-limit protection (150mA), and chip-enable logic. Its internal architecture supports operation down to 3.5V input while maintaining regulation up to 30V, with line regulation of 0.05%/V and load regulation of ±0.5% over 1–150mA.

Thermal management is enabled via junction-to-case thermal resistance of 58°C/W and built-in thermal shutdown with 20°C hysteresis. The device uses a single external EN pin for on/off control and requires no external compensation due to inherent stability with low-ESR ceramic capacitors.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.0V ±1% at 10mA - ensures stable MCU core or sensor bias without external feedback.
Input Voltage Range	3.5V to 30V - supports direct connection to automotive batteries, industrial 24V rails, or multi-cell Li-ion packs.
Max Output Current	150mA - sufficient for low-power microcontrollers, RF transceivers, or analog front-ends.
Dropout Voltage	360mV typ @ 50mA - enables regulation from 3.36V input, critical for brownout resilience in battery systems.
Ground Current	1.8µA typ @ IOUT = 0A - extends shelf life and runtime in standby/sleep modes of portable equipment.
Line Regulation	0.05%/V - minimizes output drift across wide input transients, e.g., engine cranking in automotive accessories.
Thermal Shutdown	+160°C with +20°C hysteresis - prevents latch-up during sustained overload or poor PCB heatsinking.

Pinout & Package

AP7383-30FDC-7 is housed in a 2.0mm × 2.0mm, 0.65mm height U-DFN2020-6 (Type C) package with wettable flank leads for automated optical inspection. Thermal pad on underside enhances power dissipation (θ_JA = 152°C/W, θ_JC = 58°C/W).

Pin/Terminal	Circuit Role	Design Meaning
1	VIN	Main input supply connection; accepts up to 30V DC with transient robustness.
2	GND	Power ground reference and thermal path; must be connected to large copper pour.
3	VOUT	Regulated 3.0V output; requires ≥1µF ceramic capacitor placed adjacent to pin.
4	EN	Active-high enable input; pulls device into ultra-low I_STD = 0.01µA shutdown state when low.
5, 6	NC	No-connect terminals; internally unconnected; recommended to tie to GND for thermal conduction and EMI reduction.

Key Features

Feature	Design Value
Wide Input Range	3.5V–30V operation eliminates need for pre-regulation stages in 12V/24V systems.
Ultra-Low Quiescent Current	1.8µA ground current enables >10-year battery life in IoT endpoint sensors with periodic wake-up.
Ceramic Capacitor Compatible	Stable with 1µF X5R/X7R output caps - reduces BOM count and board area vs. tantalum alternatives.
Enable Control with Shutdown Mode	EN pin reduces total system current to 0.01µA - essential for energy harvesting and zero-power retention designs.
High Accuracy & Stability	±1% V_OUT tolerance and ±100ppm/°C tempco ensure reliable ADC reference or PLL supply across -40°C to +125°C.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ULDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1703T-3002E/MB	250mA rated, 600mV dropout @ 250mA, 3.0V ±2% accuracy, SOT23-5 package	Higher current but larger dropout; lacks EN pin in base variant	Select when >150mA load or cost-sensitive SOT23 footprint required; verify thermal performance at full load.
Torex XC6210B302MR-G	150mA rated, 250mV dropout @ 100mA, 3.0V ±1%, SOT25 package, no EN pin	Lower dropout but no enable control; smaller thermal mass than U-DFN2020-6	Select for minimal dropout-critical 3.0V rails where shutdown functionality is unnecessary and SOT25 is preferred.

Compared with MCP1703T-3002E/MB and XC6210B302MR-G, the AP7383-30FDC-7 uniquely combines 30V input tolerance, enable control, ultra-low 1.8µA quiescent current, and compact U-DFN2020-6 packaging - making it optimal for space- and power-constrained industrial and portable designs requiring wide VIN flexibility.

FAQ

What is the minimum input voltage required for regulation at 3.0V output?

The AP7383-30FDC-7 requires a minimum input voltage of 3.5V to maintain regulation at its nominal 3.0V output. This 500mV headroom accommodates its worst-case dropout voltage (580mV at 50mA) plus margin for line and load transients, ensuring stable operation even under cold-start or low-battery conditions in portable systems.

Can the AP7383-30FDC-7 be used without an enable signal?

Yes - the EN pin is pulled internally to VIN via a weak current source. When left unconnected or tied to VIN, the device remains fully enabled. To disable, drive EN to ≤0.4V (logic low); this places the regulator in ultra-low 0.01µA standby mode, ideal for system-level power gating in battery-operated devices.

Is the U-DFN2020-6 (Type C) package compatible with standard reflow profiles?

Yes - the AP7383-30FDC-7's U-DFN2020-6 (Type C) package is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and processed using standard Pb-free reflow profiles (peak 260°C, 10s maximum). Its NiPdAu-plated wettable flanks support automated optical solder-joint inspection.

Does the AP7383-30FDC-7 require input and output capacitors?

Yes - the datasheet specifies 1.0µF ceramic capacitors for both C_IN and C_OUT, placed as close as possible to VIN/GND and VOUT/GND pins respectively. These capacitors ensure stability, suppress input ripple, and provide transient response; omitting them risks oscillation or failure to regulate under dynamic load conditions.
