Product details

Overview

AP7342D-3612FS6-7 from Diodes Incorporated is a dual-channel, 150mA low-dropout linear regulator with independent enable control per channel, fixed 3.6V/1.2V outputs, 75dB PSRR at 1kHz, 60µV_rms output noise (10Hz–100kHz), and ±1% output voltage accuracy over temperature. It serves as a compact, low-noise power supply for RF and digital core rails in space-constrained portable electronics.

For engineers reviewing the AP7342D-3612FS6-7 datasheet, AP7342D-3612FS6-7 pinout, AP7342D-3612FS6-7 application, or AP7342D-3612FS6-7 equivalent, key selection criteria include dual-rail sequencing capability, thermal performance in X2-DFN1212-6, dropout behavior at 150mA load per channel, and compatibility with 0.47µF ceramic output capacitors.

Technical Context

The AP7342D-3612FS6-7 integrates two independent CMOS-based LDO regulators sharing a common input but featuring separate EN1/EN2 control inputs and VOUT1/VOUT2 outputs. Each channel includes internal voltage reference, error amplifier, current limit, and auto-discharge circuitry (D-suffix variant).

It operates across 1.7V–5.25V input range with guaranteed 150mA output per channel, supports fast load transient response (≤100µs recovery), and maintains stability with minimal 0.47µF ceramic output capacitance - enabled by low-ESR optimization and internal compensation.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	3.6V (Channel 1) / 1.2V (Channel 2); fixed via internal resistor network - eliminates external feedback components and simplifies layout.
Max Output Current	150mA per channel; supports simultaneous full-load operation without derating under +85°C ambient.
PSRR	75dB at 1kHz; suppresses switching noise from upstream DC/DC converters feeding RF or analog circuitry.
Output Noise	60µV_rms (10Hz–100kHz); enables clean biasing of low-noise amplifiers and precision ADC references.
Quiescent Current	35µA (single channel active, no load); extends battery life in always-on sensor or standby subsystems.
Dropout Voltage	0.22V (at 150mA, VOUT = 3.6V); allows operation from single-cell Li-ion (3.0V min) while maintaining regulation on 3.6V rail.
Enable Thresholds	V_EN(H) ≥ 1.3V, V_EN(L) ≤ 0.5V; compatible with 1.8V/3.3V GPIO without level-shifting.

Pinout & Package

AP7342D-3612FS6-7 is housed in a thermally enhanced X2-DFN1212-6 package (1.2mm × 1.2mm, 0.4mm height) with exposed thermal pad. PCB layout requires direct connection of the thermal pad to GND plane for optimal thermal dissipation (θ_JA ≈ 220°C/W).

Pin/Terminal	Circuit Role	Design Meaning
1	VOUT1	Regulated 3.6V output; must be decoupled with ≥0.47µF ceramic capacitor placed adjacent to pin and GND.
2	VOUT2	Regulated 1.2V output; independently controllable; suitable for digital core or memory I/O supply.
3	GND	Analog/digital ground reference; low-impedance return path critical for PSRR and noise performance.
4	EN2	Active-high enable for Channel 2 (1.2V); floating prohibited - tie to VIN or controller GPIO.
5	VIN	Common input (1.7–5.25V); requires ≥0.47µF ceramic decoupling capacitor close to pin.
6	EN1	Active-high enable for Channel 1 (3.6V); supports independent power sequencing of RF and baseband supplies.

Key Features

Feature	Design Value
Dual independent enable inputs	EN1 and EN2 allow staggered startup/shutdown - e.g., power 3.6V RF chain before enabling 1.2V digital core.
Integrated auto-discharge	50Ω N-channel FET per output discharges VOUT when disabled - prevents back-powering or latch-up in multi-rail systems.
High PSRR + low noise	75dB rejection at 1kHz + 60µV_rms noise enables co-location with sensitive RF receivers without filtering overhead.
Ultra-low quiescent current	35µA (one channel active) reduces standby power in battery-backed IoT nodes and wearables.
Small-footprint packaging	X2-DFN1212-6 occupies only 1.44mm² - ideal for <10mm² PCB area budgets in smartphones and TWS earbuds.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
AP7345D-3612FS6-7	Successor device; identical pinout, same 3.6V/1.2V outputs, improved PSRR (80dB @1kHz), lower noise (45µV_rms), and extended -40°C to +125°C operating range.	Qualified for extended temperature industrial and automotive cabin applications where AP7342D is limited to +85°C.	Select AP7345D for new designs requiring higher reliability margin or broader temp range; AP7342D remains viable for cost-sensitive consumer-grade production.
Torex XC6210B3612MR-G	Fixed dual-output LDO in USP-6B package; 3.6V/1.2V outputs, 100mA per channel, 65dB PSRR, 40µV_rms noise, no auto-discharge.	Lacks independent enable and discharge functions - requires external MOSFETs for sequencing and rail discharge.	Choose XC6210B only if footprint compatibility with USP-6B is mandatory and system-level discharge is already implemented externally.

Compared with AP7342D-3612FS6-7, AP7345D offers measurable improvements in noise and temperature range without layout changes, while XC6210B trades integration for smaller package size but increases design complexity with external discharge circuitry.

FAQ

What is the thermal pad connection requirement for AP7342D-3612FS6-7?

The exposed thermal pad must be soldered to a dedicated GND copper pour on the PCB - not used as sole GND electrode. Minimum recommended copper area is 25mm² with ≥4 thermal vias (0.3mm diameter) connecting to inner-layer GND planes. This configuration achieves θ_JA ≈ 220°C/W and prevents thermal shutdown at 150mA per channel under +85°C ambient.

Can AP7342D-3612FS6-7 operate with only one channel enabled?

Yes - EN1 and EN2 are fully independent. Driving EN1 high and EN2 low powers only the 3.6V rail while placing the 1.2V regulator in shutdown (ISTANDBY ≤ 1.0µA). This mode is validated per datasheet Section 4.2 and maintains full PSRR/noise specs on the active channel.

Is the 3.6V/1.2V output combination available in non-discharge variants?

No - the "D" suffix in AP7342D-3612FS6-7 explicitly denotes integrated auto-discharge functionality on both outputs. Non-discharge versions use part numbers without "D" (e.g., AP7342-3612FS6-7), but that specific combination is not listed in the official ordering table; only D-suffix variants are documented for 3.6V/1.2V pairing.

What minimum output capacitance is required for stability?

A minimum of 0.47µF X5R/X7R ceramic capacitor is required per output, placed within 2mm of VOUT and GND pins. The device remains stable with ESR as low as 1mΩ and does not require series resistance; larger values (e.g., 1µF–4.7µF) improve transient response but do not affect loop stability.
