Product details

Overview

ZXCL260E5 from Diodes Incorporated is a 2.6V fixed-output, micropower low-dropout linear regulator in SOT25 (5-pin) package, designed for space-constrained battery-powered systems. It delivers up to 150mA output current with 85mV dropout at 50mA load, 50µA ground pin current at full load, and <10nA shutdown current-enabling ultra-low-power operation in portable instrumentation and handheld devices.

For engineers reviewing the ZXCL260E5 datasheet, ZXCL260E5 pinout, ZXCL260E5 application, or ZXCL260E5 equivalent, key selection criteria include its 2.6V output accuracy (±3%), thermal/overcurrent protection, active-HIGH enable logic compatible with TTL/CMOS, and stability with 1µF ceramic output capacitors without requiring bypass components.

Technical Context

The ZXCL260E5 uses a PMOS pass transistor architecture enabling low dropout and minimal ground current across load and temperature ranges. Its internal bandgap reference (1.25V), error amplifier, and buffer stage provide precise output regulation independent of input voltage variation within 2.0–5.5V range.

Enable control is implemented via a dedicated TTL/CMOS-compatible input with 150mV hysteresis and no internal VIN clamp diode-allowing independent biasing up to 10V. Thermal shutdown activates at ≥125°C junction temperature, cycling until overload removal.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	2.6V ±3% - tightly regulated nominal output under 1mA–100mA load and -40°C to +85°C ambient
Dropout Voltage	85mV at 50mA - enables stable regulation even when VIN is only 2.685V, critical for single-cell Li-ion or alkaline systems
Ground Pin Current	50µA at 150mA load - minimizes total system quiescent power, extending battery life in always-on monitoring circuits
Shutdown Current	<10nA - reduces standby power to negligible levels during host-controlled sleep modes
Enable Logic Threshold	V_ENH = 2.2V min, V_ENL = 0.8V max - ensures reliable activation/deactivation with standard 3.3V or 5V GPIOs
PSRR	70dB at 1kHz (C_OUT = 1µF) - suppresses supply ripple from noisy DC-DC stages feeding sensitive analog subsystems
Thermal Shutdown	125°C activation - protects against sustained overloads or high VIN–VOUT differentials without external circuitry

Pinout & Package

SOT25 (5-pin) package: 2.8mm × 1.6mm × 1.1mm body, gull-wing leads, JEDEC MO-229 compliant. Designed for high-density PCB layouts with thermal pad compatibility (θ_JA ≈ 180–300°C/W depending on board copper area).

Pin/Terminal	Circuit Role	Design Meaning
VIN	Input Supply	Primary power input (2.0–5.5V); connects to upstream source or filtering capacitor
GND	Ground Reference	System ground return path for both regulator core and load current
EN	Enable Control	Active-HIGH logic input; drives internal bias circuitry to activate or disable regulation
N/C	No Connection	Internally unconnected pin; must remain floating or tied to GND per layout guidelines
VO	Regulated Output	Stable 2.6V supply rail; requires ≥1µF ceramic capacitor (X7R dielectric recommended) for stability

Key Features

Feature	Design Value
No-load stability	Maintains regulation with zero output current-enables direct powering of CMOS RAM or real-time clocks without dummy loads
Low-noise operation	50µV_RMS (10Hz–100kHz) without bypass capacitor-reduces need for additional filtering in audio or sensor signal chains
Robust protection	Integrated thermal shutdown and current limiting (160–800mA range)-eliminates need for external fault management circuitry
Capacitor flexibility	Stable with all ceramic, tantalum, and electrolytic output capacitors ≥1µF-simplifies BOM and layout across product generations
Ultra-small footprint	SOT25 package occupies 4.5mm² board area-half the size of legacy SOT23 LDOs, ideal for wearables and miniaturized IoT nodes

Applications

Use Scenario: Supplying 2.6V to RF transceiver ICs and tactile feedback drivers in sub-GHz remote controls with coin-cell batteries.

IC Role / Device Role / Timing Role: Regulated power source enabling fast wake-up from deep sleep (<10nA shutdown) while maintaining RF output consistency during transmit bursts.

Use Value: Active-HIGH EN pin synchronizes with MCU GPIO to gate power precisely-reducing average system current by >99% during idle intervals.

Handheld Test Meters

Industrial Data Loggers

Use Scenario: Providing clean 2.6V bias to precision voltage references and multiplexed sensor interfaces in pocket-sized multimeters.

IC Role / Device Role / Timing Role: Low-noise, no-bypass-regulator for reference voltage generation-minimizing measurement drift caused by supply ripple or ESR variations.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
AP2121AK-2.6TRG1	2.6V output, 300mA I_OUT, 120mV dropout at 150mA, SOT23-5 package	Higher output current capability but larger dropout and ground current (120µA @150mA)	Select when higher load headroom is required and board space allows SOT23-5; avoid if <100µA quiescent budget is mandatory.
AP7115-26SEG-7	2.6V output, 500mA I_OUT, 250mV dropout at 300mA, SOT23-5 package, integrated soft-start	Higher current and integrated soft-start, but significantly higher quiescent current (25µA typical no-load)	Prefer for motor-driven peripherals or high-capacitance loads where inrush control matters more than ultra-low standby power.

Compared with ZXCL260E5, AP2121AK-2.6TRG1 trades lower quiescent power for higher output current, while AP7115-26SEG-7 adds soft-start at the cost of 25× higher no-load current-making ZXCL260E5 uniquely suited for multi-year battery life in intermittent-sensing applications.

FAQ

Is ZXCL260E5 still recommended for new designs?

No. Diodes Incorporated marks ZXCL260E5 as "Not Recommended for New Design" (NRND) per DS33439 Rev. 10. It remains available for legacy support and existing production, but AP2121AK-2.6TRG1 is the designated replacement for new designs requiring 2.6V output in SOT23-5 format.

What is the minimum input voltage required for regulation at 2.6V output?

The datasheet specifies VIN(min) > VOUT(nom) + 0.5V for normal operation, so minimum input is 3.1V. However, regulation begins when VIN exceeds ~1.3V; below 3.1V, the device operates in dropout with reduced headroom-verified by 85mV dropout at 50mA load.

Can ZXCL260E5 drive a 150mA load continuously without thermal shutdown?

Yes, but thermal performance depends on PCB layout. With a 2-inch² board, SOT25's θ_JA is ~180°C/W. At 150mA and 5.5V–2.6V differential (2.9V drop), power dissipation is 435mW-exceeding the 450mW package limit marginally. Derating is advised above 60°C ambient.

Does the N/C pin require any PCB connection?

No. Pin 2 (N/C) is internally unconnected. The datasheet explicitly states it "should be left open circuit or connected to pin 3" (GND). Floating is preferred; grounding is acceptable but provides no functional benefit and may slightly increase parasitic capacitance.
