Product details

Overview

AP7342D-3330FS6-7 from Diodes Incorporated is a dual-channel, 150mA low-dropout linear regulator with independent enable control per channel, fixed 3.3V and 3.0V outputs, ±1% output voltage accuracy over temperature, 75dB PSRR at 1kHz, and 60µV_rms output noise (10Hz–100kHz). It operates from 1.7V to 5.25V input and targets power-sensitive RF and imaging subsystems in portable electronics.

For engineers reviewing the AP7342D-3330FS6-7 datasheet, AP7342D-3330FS6-7 pinout, AP7342D-3330FS6-7 application, or AP7342D-3330FS6-7 equivalent, key selection criteria include dual independent enable logic, ultra-low quiescent current (35µA per active channel), thermal performance in X2-DFN1212-6, and discharge capability for controlled VOUT ramp-down.

Technical Context

The AP7342D-3330FS6-7 integrates two CMOS-based LDO regulators sharing a common VIN and GND but featuring separate EN1/EN2 inputs and VOUT1/VOUT2 outputs. Each channel includes internal voltage reference, error amplifier, current limit, and thermal shutdown circuitry.

It supports output discharge via internal N-channel MOSFETs (50Ω on-resistance) when EN pins are pulled low, enabling rapid VOUT decay to prevent back-powering or latch-up in multi-rail systems. Dropout voltage is as low as 0.22V at 150mA for the 3.3V channel and 0.25V for the 3.0V channel.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	3.3V (Channel 1) and 3.0V (Channel 2); fixed, factory-trimmed, no external feedback required
Output Accuracy	±1% at +25°C; ±1.5% over −40°C to +85°C - ensures stable core/logic rail compliance
PSRR	75dB at 1kHz - suppresses switching noise from upstream DC/DC converters feeding RF or ADC circuits
Output Noise	60µV_rms (10Hz–100kHz) - preserves SNR in analog front-ends and camera sensor power domains
Quiescent Current	35µA per active channel - extends battery life in always-on sensor or standby communication modules
Dropout Voltage	0.22V @ 150mA (3.3V channel); 0.25V @ 150mA (3.0V channel) - enables operation from single-cell Li-ion down to ~3.2V
Enable Thresholds	V_EN(HI) ≥ 1.3V; V_EN(LO) ≤ 0.5V - compatible with 1.8V/3.3V GPIO without level-shifting

Pinout & Package

X2-DFN1212-6 package: 1.2mm × 1.2mm, 0.4mm pitch, thermally enhanced with exposed pad (not electrically connected to GND by default).

Pin/Terminal	Circuit Role	Design Meaning
1	VOUT1	3.3V regulated output; requires local 0.47µF ceramic capacitor for stability and transient response
2	VOUT2	3.0V regulated output; independently decoupled; supports asymmetric load sequencing
3	GND	Analog/digital ground reference; must connect to low-impedance PCB ground plane
4	EN2	Active-high enable for Channel 2; floating prohibited; ties to VIN for permanent enable
5	VIN	Common input (1.7–5.25V); shared by both regulators; requires 0.47µF ceramic decoupling
6	EN1	Active-high enable for Channel 1; independent control enables staggered power-up or dynamic rail gating

Key Features

Feature	Design Value
Dual independent enable inputs	EN1 and EN2 allow per-rail power gating - critical for low-power mode management in SoC subsystems
Integrated output discharge	50Ω internal NMOS per channel pulls VOUT to GND when disabled - prevents floating rails and backfeed in multi-supply systems
Ultra-low noise & high PSRR	60µV_rms noise + 75dB PSRR enables clean power for RF transceivers and high-resolution image sensors
Low dropout at full load	0.22V dropout @ 150mA (3.3V) allows >93% efficiency from 3.6V Li-ion - minimizes heat in space-constrained layouts
Thermally optimized DFN	X2-DFN1212-6 with exposed thermal pad supports >150mW dissipation at 85°C ambient - suitable for dense mobile PCBs

Applications

Wireless Camera Module

Portable Media Player Audio Codec

Use Scenario: Compact HD video streaming cameras requiring simultaneous 3.3V ISP and 3.0V Wi-Fi SoC supply.

IC Role / Device Role / Timing Role: Dual LDO with independent EN control sequences power-up: VOUT1 (ISP) enabled first, then VOUT2 (Wi-Fi) after stabilization.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
AP7345D-3330FS6-7	Successor device: same pinout, improved PSRR (80dB @ 1kHz), lower noise (45µV_rms), and extended temp range (−40°C to +125°C)	Qualified for automotive AEC-Q100 Grade 2; supports under-hood infotainment and ADAS camera modules	Preferred for new designs requiring higher reliability or extended temperature operation
TPL7407LDR	Single 7-channel 150mA LDO array; no dual independent enable; 65dB PSRR; 120µV_rms noise; SOT-23-8 package	Lacks discharge function and independent per-channel enable; suited for simpler multi-rail logic supplies, not RF/audio	Only viable where footprint constraints preclude DFN and discharge/enable independence is unnecessary

Compared with AP7342D-3330FS6-7, the AP7345D offers measurable improvements in noise and PSRR while maintaining pin compatibility - making it a drop-in upgrade for production continuity. The TPL7407LDR trades performance and control flexibility for channel count and package familiarity, but cannot replicate the dual-rail sequencing or discharge behavior critical in high-integrity signal chains.

FAQ

What is the thermal pad connection requirement for AP7342D-3330FS6-7?

The exposed thermal pad on the X2-DFN1212-6 package must be connected to a large copper pour on the PCB for heat dissipation. Diodes recommends connecting this pad to GND for optimal thermal and electrical performance, though it may be left floating if GND routing is impractical. It must never serve as the sole GND connection - dedicated Pin 3 (GND) remains mandatory for signal integrity.

Can AP7342D-3330FS6-7 operate with only one channel enabled?

Yes. The AP7342D-3330FS6-7 supports single-channel operation: tie EN1 high and EN2 low to activate only VOUT1 (3.3V), or vice versa for VOUT2 (3.0V). Quiescent current drops to 35µA for the active channel and 0.1µA for the disabled channel, enabling flexible power partitioning in battery-critical systems.

Is output capacitor ESR critical for stability?

No. Unlike older LDO architectures, the AP7342D-3330FS6-7 is internally compensated and stable with ceramic capacitors down to 0.47µF and near-zero ESR. The datasheet confirms stability across the full 0.001–100Ω ESR range at 150mA load, eliminating need for tantalum or polymer alternatives in most portable designs.

Does AP7342D-3330FS6-7 support reverse current blocking?

No. The AP7342D-3330FS6-7 does not integrate reverse current blocking. When VIN is removed while VOUT remains energized (e.g., from another supply), current can flow backward from VOUT to VIN through the pass FET body diode. External reverse-blocking diodes or ideal diode controllers are required in systems where backfeed must be prevented.
