Product details

Overview

AP7342D-1815FS6-7 from Diodes Incorporated is a dual-channel, 150mA low-dropout linear regulator with independent enable control per channel, delivering fixed 1.8V and 1.5V outputs in a 1.2mm × 1.2mm X2-DFN1212-6 package. It features ±1% output voltage accuracy over temperature, 75dB PSRR at 1kHz, 60µV_rms output noise (10Hz–100kHz), and ultra-low 35µA quiescent current in single-channel active mode - optimized for RF supply rails in compact portable media players.

For engineers reviewing the AP7342D-1815FS6-7 datasheet, AP7342D-1815FS6-7 pinout, AP7342D-1815FS6-7 application, or AP7342D-1815FS6-7 equivalent, key selection criteria include dual independent enable logic, discharge-capable output architecture, thermal performance in 1.2mm² footprint, and compatibility with 0.47µF ceramic output capacitors for fast load transient response.

Technical Context

The AP7342D-1815FS6-7 integrates two CMOS-based LDO regulators sharing a common input but with fully independent enable inputs (EN1/EN2), output pins (VOUT1/VOUT2), and internal feedback networks. Each channel uses a precision voltage reference and error amplifier to maintain regulation under line/load transients.

It implements built-in auto-discharge functionality via integrated N-channel MOSFETs (50Ω typical on-resistance) that actively pull VOUT1/VOUT2 to GND when respective EN pins are driven low - eliminating residual voltage hold-up without external components. Dropout voltage ranges from 0.22V to 0.59V depending on output voltage and load.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	1.8V (Channel 1), 1.5V (Channel 2); factory-trimmed fixed outputs eliminate external resistor networks.
Output Accuracy	±1% at +25°C, ±1.5% over −40°C to +85°C; ensures stable core/logic rail tolerance in battery-powered systems.
PSRR	75dB at 1kHz; suppresses switching noise from adjacent DC-DC converters feeding shared input rail.
Output Noise	60µV_rms (10Hz–100kHz); enables clean power for RF front-end ICs and high-resolution ADCs.
Quiescent Current	35µA (one channel active, one disabled); extends battery life in always-on subsystems like Bluetooth co-processors.
Dropout Voltage	0.30V at 150mA for 1.8V output; allows operation down to 2.1V input - compatible with single-cell Li-ion (2.7–4.2V) and Li-polymer batteries.
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-1815FS6-7 is housed in a thermally enhanced 6-pin X2-DFN1212-6 package (1.2mm × 1.2mm, 0.4mm height) with an exposed thermal pad. The pad must be connected to PCB ground plane for optimal thermal dissipation (θ_JA = 220°C/W).

Pin/Terminal	Circuit Role	Design Meaning
1	VOUT1	1.8V regulated output; requires local 0.47µF ceramic capacitor to GND for stability and transient response.
2	VOUT2	1.5V regulated output; independently controllable; same capacitor requirement as VOUT1.
3	GND	Analog/digital ground reference; must connect directly to low-impedance PCB ground plane.
4	EN2	Active-high enable for Channel 2; drives VOUT2; floating prohibited - tie to VIN or GND if unused.
5	VIN	Common input (1.7–5.25V); shared by both regulators; requires 0.47µF decoupling capacitor to GND.
6	EN1	Active-high enable for Channel 1; drives VOUT1; independent control enables staggered power-up sequencing.

Key Features

Feature	Design Value
Dual independent enable control	EN1/EN2 allow per-channel power gating - critical for subsystem-level power management in portable SoC designs.
Built-in output discharge	50Ω internal N-MOSFETs actively discharge VOUT1/VOUT2 on disable - eliminates need for external bleed resistors and reduces BOM count.
Ultra-low noise & high PSRR	60µV_rms noise + 75dB PSRR enables direct powering of sensitive RF ICs (e.g., Wi-Fi/BT transceivers) without additional filtering.
Small-footprint packaging	X2-DFN1212-6 (1.2mm × 1.2mm) supports high-density layouts in space-constrained applications like TWS earbuds and smartwatches.
Low dropout across full range	0.22–0.59V dropout enables efficient operation from partially discharged batteries - extends usable runtime in 1-cell systems.

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-1815FS6-7	Successor device; identical pinout, same 1.8V/1.5V outputs, improved PSRR (80dB @ 1kHz), lower noise (45µV_rms), and AEC-Q200 qualification option.	Designed for new designs requiring extended automotive temperature range (−40°C to +125°C) or higher reliability certification.	Select AP7345D for new projects - Diodes explicitly states AP7342 is not recommended for new designs.
Torex XC6216D1815MR-G	Pin-compatible dual LDO; same 1.8V/1.5V outputs; 70dB PSRR, 40µV_rms noise, but no built-in discharge; requires external resistors for discharge path.	Suitable where discharge is not required or where Torex's smaller 0.8mm × 0.8mm USP-6B package is preferred.	Choose XC6216D only if discharge function is unnecessary and board space is more constrained than thermal budget.

Compared with AP7342D-1815FS6-7, AP7345D offers measurable improvements in noise and PSRR while maintaining drop-in compatibility, whereas XC6216D trades discharge capability for slightly lower noise and smaller size - making AP7345D the preferred upgrade path and XC6216D a niche alternative for discharge-free layouts.

FAQ

What is the thermal pad connection requirement for AP7342D-1815FS6-7?

The exposed thermal pad on the X2-DFN1212-6 package must be soldered to a dedicated PCB copper pour connected to GND. This pad is not electrically functional as a ground terminal but serves solely for thermal conduction - using it as the sole GND return path violates layout guidelines and degrades noise performance.

Can AP7342D-1815FS6-7 operate with only one output enabled?

Yes - EN1 and EN2 are fully independent. Driving EN1 high and EN2 low enables only VOUT1 (1.8V), drawing just 35µA quiescent current. This configuration is validated in the datasheet and commonly used to power auxiliary circuits while keeping main rails inactive.

Is external output capacitance mandatory, and what value is recommended?

Yes - a minimum 0.47µF ceramic capacitor is required per output (VOUT1 and VOUT2) placed within 2mm of the respective pin and GND. Lower ESR capacitors improve transient response, but values below 0.47µF risk instability per the datasheet's stability analysis and ESR vs. output current graph.

Does AP7342D-1815FS6-7 support reverse current blocking?

No - the AP7342D-1815FS6-7 does not integrate reverse current blocking. When VIN drops below VOUT, current can flow backward from output to input. For applications requiring reverse blocking (e.g., battery backup paths), an external Schottky diode or ideal diode controller must be added in series with VIN.
