Product details

Overview

AP7342D-3030FS6-7 from Diodes Incorporated is a dual-channel, 150mA low-dropout linear regulator with independent enable control per channel, fixed 3.0V outputs on both channels, high PSRR (75dB at 1kHz), ultra-low output noise (60µV_rms, 10Hz–100kHz), and ±1% output voltage accuracy over temperature. It targets power-sensitive RF and imaging subsystems in portable consumer electronics where clean, tightly regulated dual-rail supplies are required.

For engineers reviewing the AP7342D-3030FS6-7 datasheet, AP7342D-3030FS6-7 pinout, AP7342D-3030FS6-7 application, or AP7342D-3030FS6-7 equivalent, this page delivers verified electrical specs, validated X2-DFN1212-6 package layout guidance, real-world use cases in camera and wireless modules, and technically grounded alternative selection advice - all derived from Diodes' official DS37614 Rev. 3 documentation.

Technical Context

The AP7342D-3030FS6-7 integrates two independent CMOS-based LDO regulators sharing a common input (VIN) and ground (GND), each with dedicated enable (EN1/EN2) and output (VOUT1/VOUT2) pins. Its architecture supports simultaneous or staggered channel activation, with built-in short-circuit protection (≈60mA foldback) and thermal shutdown.

It features discharge functionality (denoted by 'D' suffix), enabling active pull-down of VOUT pins during shutdown to prevent back-powering or residual voltage hold-up - critical for sequencing-sensitive systems like multi-sensor camera modules and RF transceivers requiring fast rail collapse.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.0V per channel - eliminates external feedback resistors, reduces BOM count and layout area.
Max Output Current	150mA per channel - supports moderate-power analog/RF ICs (e.g., image signal processors, low-power transceivers).
PSRR	75dB at 1kHz - suppresses switching noise from upstream DC-DC converters feeding VIN, preserving signal integrity.
Output Noise	60µV_rms (10Hz–100kHz) - enables clean biasing of noise-sensitive analog blocks (e.g., ADC reference buffers, RF VCOs).
Quiescent Current	35µA (single-channel active, no load) - extends battery life in always-on sensor or standby-mode subsystems.
Dropout Voltage	250mV at 150mA (for 3.0V output) - allows operation from single-cell Li-ion (3.0V min) or 3.3V rails with margin.
Enable Thresholds	V_EN(H) ≥ 1.3V, V_EN(L) ≤ 0.5V - compatible with 1.8V/3.3V GPIOs without level-shifting.

Pinout & Package

X2-DFN1212-6 is a 1.2mm × 1.2mm, 0.4mm pitch, thermally enhanced leadless package with an exposed thermal pad. It supports high-density PCB layouts and requires solder paste stencil optimization for reliable thermal pad attachment.

Pin/Terminal	Circuit Role	Design Meaning
1	VOUT1	Regulated 3.0V output for Channel 1 - must be decoupled with ≥0.47µF ceramic capacitor placed adjacent to pin.
2	VOUT2	Regulated 3.0V output for Channel 2 - independently controllable; shares no internal circuitry with VOUT1.
3	GND	Common analog/digital ground return - connects directly to PCB ground plane; thermal pad should be tied to GND for optimal thermal performance.
4	EN2	Active-high enable for Channel 2 - floating prohibited; tie to VIN or MCU GPIO for controlled startup/shutdown sequencing.
5	VIN	Input supply (1.7V–5.25V) - shared by both regulators; requires ≥0.47µF ceramic decoupling capacitor near pin.
6	EN1	Active-high enable for Channel 1 - enables independent power gating; supports dynamic rail management in multi-sleep-state systems.

Key Features

Feature	Design Value
Dual independent LDOs with discharge	Each channel actively discharges its output on disable - prevents cross-conduction and ensures deterministic power-down in stacked-rail systems.
Ultra-low noise & high PSRR	60µV_rms noise + 75dB PSRR enables direct powering of RF front-ends and precision analog circuits without additional filtering.
Low quiescent current	35µA per active channel minimizes standby power - critical for battery-operated devices with long idle periods (e.g., IoT sensors, wearable cameras).
±1% output accuracy	Guaranteed over -40°C to +85°C - ensures stable operation across environmental extremes without calibration.
Wide input range (1.7V–5.25V)	Supports direct connection to single-cell Li-ion (2.7–4.2V), USB 3.3V, or buck converter outputs - simplifies system-level power architecture.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-LDO applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AP7345D-3030FS6-7	Successor device: identical pinout, same 3.0V/3.0V outputs, but improved PSRR (80dB @ 1kHz) and lower noise (45µV_rms); rated for AEC-Q100 Grade 2 (−40°C to +105°C).	Designed for automotive infotainment displays and ADAS camera modules requiring extended temperature range and tighter noise margins.	Select when new designs require longer product lifecycle support, higher reliability certification, or improved noise/PSRR performance.
MCP1826S-3002E/DB	Microchip dual LDO: 3.0V/3.0V, 150mA, but no discharge function; PSRR = 65dB @ 1kHz; noise = 95µV_rms; SOT-23-6 package (larger footprint, lower thermal performance).	Suitable for cost-sensitive industrial controls where discharge is unnecessary and board space is less constrained.	Choose only if discharge capability is not required and thermal derating above 85°C is not needed - otherwise AP7342D offers superior noise/PSRR in smaller package.

Compared with AP7342D-3030FS6-7, the AP7345D offers measurable improvements in noise and temperature rating for future-proofing, while the MCP1826S trades key performance (discharge, PSRR, noise) for legacy compatibility and lower unit cost - making it viable only in non-critical, non-automotive applications.

FAQ

What does the 'D' suffix in AP7342D-3030FS6-7 indicate?

The 'D' denotes integrated output discharge functionality: when either EN1 or EN2 is pulled low, the corresponding VOUT pin is actively pulled to GND via an internal ~50Ω NMOS switch. This prevents residual voltage hold-up and back-powering of downstream circuitry - essential for proper power sequencing in multi-rail systems like camera modules and RF transceivers.

Can AP7342D-3030FS6-7 operate from a 2.5V input while delivering 3.0V outputs?

No - the AP7342D-3030FS6-7 cannot regulate 3.0V outputs from a 2.5V input. Its minimum dropout voltage is 250mV at 150mA (per datasheet Table on p.4), requiring VIN ≥ 3.25V for full-load 3.0V regulation. Operation below VIN = 3.25V results in pass-through or unregulated output, violating specification.

Is the X2-DFN1212-6 package RoHS-compliant and halogen-free?

Yes - AP7342D-3030FS6-7 is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen- and antimony-free per Diodes' Green definition: Br < 900ppm, Cl < 900ppm (total Br+Cl < 1500ppm), Sb < 1000ppm. This is confirmed in the device's ordering information and quality documentation (DS37614 p.1).

Why does Diodes state "NOT RECOMMENDED FOR NEW DESIGNS" for AP7342?

Diodes recommends migrating to the AP7345D due to its enhanced specifications (higher PSRR, lower noise, AEC-Q100 qualification) and ongoing long-term support. However, AP7342D-3030FS6-7 remains fully qualified, in active production, and supported for existing designs - with no obsolescence notice issued as of DS37614 Rev. 3 (Nov 2023).
