Product details
Overview
ZXCL5213V30H5TA from Diodes Incorporated is a micropower 3.0V fixed-output low-dropout linear regulator in SC70-5/SOT353 package, featuring 85mV dropout at 50mA, 50µA ground current at 150mA load, and active-high enable control. It delivers stable regulation for battery-powered portable electronics requiring ultra-low quiescent power and compact footprint.
For engineers reviewing the ZXCL5213V30H5TA datasheet, ZXCL5213V30H5TA pinout, ZXCL5213V30H5TA application, or ZXCL5213V30H5TA equivalent, key selection criteria include dropout voltage under light-to-moderate load, shutdown current (<10nA), no-load stability, thermal shutdown threshold (125°C), and compatibility with 1µF ceramic output capacitors without external bypass.
Technical Context
The ZXCL5213V30H5TA employs a PMOS pass transistor architecture enabling low dropout and near-constant ground current across load and input voltage ranges. Its bandgap reference and error amplifier deliver ±2% initial output accuracy and –15 ppm/°C temperature coefficient.
It integrates TTL/CMOS-compatible enable logic with 150mV hysteresis, thermal shutdown activation at ≥125°C, and current limiting with typical trip at 230mA (min 160mA, max 800mA). The device operates stably with 1µF X7R ceramic output capacitors and requires no external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0V ±2% at 1mA–100mA load; maintains regulation down to no-load condition |
| Dropout Voltage | 85mV at 50mA load; enables operation with VIN as low as 3.085V while sustaining 3.0V output |
| Ground Current | 50µA at full 150mA load; ensures minimal battery drain in active mode |
| Shutdown Current | <10nA at VEN = 0V; supports multi-year battery life in standby states |
| Enable Threshold | VENH ≥ 2.2V (TTL/CMOS compatible); VENL ≤ 0.8V; 150mV hysteresis prevents chatter |
| Thermal Shutdown | Activates at ≥125°C junction temperature; auto-recovers upon cooling |
| PSRR | 60dB at 1kHz (with 1µF output cap); suppresses supply ripple in noise-sensitive analog rails |
Pinout & Package
Package: SC70-5 / SOT353 (H5), 2.1mm × 1.3mm × 0.95mm body, 0.65mm pitch, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input supply connection | Accepts 2.0V–5.5V input; internal diode anode tied to VO limits reverse current to 5mA continuous |
| GND (Pin 2) | Power ground reference | Low-impedance return path for load and bias currents; critical for PSRR and noise performance |
| EN (Pin 3) | Active-high enable control | Drives internal bias circuits; floating or pulled high enables regulation; pulled low disables output |
| N/C (Pin 4) | No-connect terminal | Must be left open or connected to Pin 3 (EN); no internal connection or function |
| VO (Pin 5) | Regulated output | Delivers 3.0V ±2%; stable with ≥1µF X7R ceramic capacitor; supports no-load CMOS RAM retention |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 85mV @ 50mA enables use in single-cell Li-ion (3.0–4.2V) or two-cell alkaline systems |
| Micropower ground current | 50µA @ 150mA allows >10-year battery life in always-on sensor nodes with 200mAh coin cell |
| No-load stability | Regulates continuously with zero output load-essential for backup power to SRAM or RTC circuits |
| Low-noise operation | 50µVRMS (10Hz–100kHz) without bypass capacitor simplifies layout in audio and precision ADC supplies |
| Robust protection | Integrated thermal shutdown + current limit tolerates indefinite output short to GND or VO |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2121AK-3.0TRG1 | SOT23-5 package; higher 120µA ground current at 150mA; 120mV dropout at 50mA | Larger footprint; less suitable for ultra-dense portable designs | Preferred where SOT23-5 board space and legacy footprint compatibility outweigh micropower needs |
| AP7115-30SEG-7 | SC70-5 package; 1.2V reference-based adjustable output; requires external resistors; 100mV dropout at 50mA | Requires BOM addition of two precision resistors; less accurate than fixed 3.0V option | Chosen when system requires multiple output voltages from one regulator family or fine-tuned voltage trimming |
Compared with ZXCL5213V30H5TA, AP2121AK-3.0TRG1 trades micropower efficiency for broader design reuse in SOT23-5 layouts, while AP7115-30SEG-7 sacrifices fixed-voltage accuracy and simplicity for configurability-neither matches the combination of SC70-5 size, 85mV dropout, and sub-50µA ground current.

FAQ
What is the minimum input voltage required for regulation at full 150mA load?
The ZXCL5213V30H5TA requires VIN ≥ VOUT + VDO = 3.0V + 0.28V = 3.28V at 100mA load (per datasheet max dropout), and ≥3.085V at 50mA. For reliable 150mA operation, VIN must exceed 3.28V to maintain regulation margin, as dropout rises with load current per the typical characteristics curve.
Can the N/C pin (Pin 4) be used as a second ground connection?
No. Pin 4 is explicitly designated "No Connection" and has no internal bond wire or silicon connection. The datasheet states it "should be left open circuit or connected to pin 3" (EN). Using it as ground violates the pinout definition and may cause unpredictable behavior or violate internal layout constraints.
Is an input capacitor mandatory, and what value is recommended?
Yes-an input capacitor is recommended to filter supply noise and improve ripple rejection. A 1µF ceramic (X7R dielectric) capacitor placed close to VIN and GND pins is specified in the datasheet. Larger values improve high-frequency PSRR but are not required for basic stability, unlike some LDOs that mandate minimum ESR.
Does the device support reverse current protection when VOUT > VIN?
The ZXCL5213V30H5TA contains an inherent parasitic diode (anode at VO, cathode at VIN) that conducts if VOUT exceeds VIN by >0.6V. This is not protective-it permits reverse current up to 5mA continuous. For robust reverse polarity or back-drive protection, an external Schottky diode in series with VIN is required per the application note.
