Product details
Overview
MIC5370-PPYMT-TR from Micrel is a dual-channel, fixed-output 3.0V/3.0V low-dropout linear regulator (LDO) delivering 150mA per channel in a 6-pin 1.6mm × 1.6mm Thin MLF® package. It features ±2% initial output accuracy, 155mV dropout at full load (150mA), and ultra-low ground current of 32µA per LDO - optimized for battery-powered portable electronics requiring compact dual-rail power with fast transient response and high PSRR.
For engineers reviewing the MIC5370-PPYMT-TR datasheet, MIC5370-PPYMT-TR pinout, MIC5370-PPYMT-TR application, or MIC5370-PPYMT-TR equivalent, this device serves as a space-constrained, dual-output voltage regulation solution for camera modules, baseband processors, and RF subsystems where independent enable control, zero-off-mode shutdown, and stability with 1µF ceramic capacitors are critical design requirements.
Technical Context
The MIC5370-PPYMT-TR integrates two independent CMOS-based LDO regulators sharing a common input (VIN) and ground (GND), each with dedicated active-high enable inputs (EN1, EN2) and separate outputs (VOUT1, VOUT2). Its architecture supports simultaneous or staggered activation, with no cross-regulator coupling in regulation or transient response.
Each LDO employs internal bandgap reference and error amplifier feedback to maintain tight DC accuracy (±2% typ.) across –40°C to +125°C, while achieving 60dB ripple rejection at 1kHz and 200µVRMS output noise (10Hz–100kHz). Thermal shutdown and foldback current limiting protect against fault conditions without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V / 3.0V - dual identical rails for symmetric core/peripheral supply in portable SoC systems. |
| Max Output Current | 150mA per channel - sufficient to power DSP cores, image sensors, or RF transceivers without thermal derating in standard PCB layouts. |
| Dropout Voltage | 155mV @ 150mA - enables operation down to VIN = 3.15V while maintaining regulation on both 3.0V rails. |
| Ground Current | 32µA per LDO (typ.) - minimizes quiescent power loss during active operation, extending battery life in always-on subsystems. |
| Accuracy | ±2% initial tolerance - ensures reliable logic-level compliance for 3.0V I/O domains without post-production calibration. |
| PSRR | 60dB @ 1kHz - suppresses switching noise from upstream DC/DC converters feeding VIN, critical for analog/RF sections. |
| Stability | With ≥1µF X5R/X7R ceramic output capacitor - eliminates need for bulk electrolytics, reducing board area and cost. |
Pinout & Package
Package: 6-pin 1.6mm × 1.6mm Thin MLF® (Pb-free, RoHS-compliant), exposed thermal pad internally connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Supply Input | Common input for both LDOs; must be decoupled with ≥1µF ceramic capacitor to GND for stability. |
| 2 - GND | Ground Reference | Power and signal return; connects to exposed EPAD for thermal dissipation and low-impedance grounding. |
| 3 - EN2 | Enable Input (LDO2) | Active-high logic control; drives LDO2 output to high-impedance state when pulled low, enabling independent power sequencing. |
| 4 - EN1 | Enable Input (LDO1) | Active-high logic control; allows independent startup/shutdown of first rail, e.g., for core voltage before I/O. |
| 5 - VOUT2 | LDO2 Output | Regulated 3.0V supply for secondary circuitry (e.g., camera interface, memory I/O); stable with 1µF ceramic cap. |
| 6 - VOUT1 | LDO1 Output | Regulated 3.0V supply for primary load (e.g., baseband processor core); shares same accuracy and transient performance as VOUT2. |
Key Features
| Feature | Design Value |
|---|---|
| Independent Enable Control | EN1 and EN2 allow precise power-up/down sequencing between two 3.0V domains - essential for avoiding bus contention or latch-up in multi-rail SoCs. |
| Zero-Off-Mode Shutdown | Draws ≤1µA total when both EN pins are low - eliminates standby leakage in sleep modes of handheld devices. |
| Low-ESR Ceramic Stability | Guaranteed stable with 1µF X5R/X7R output capacitors - avoids large tantalum or aluminum electrolytics, reducing footprint and cost. |
| Thermal & Current Protection | Integrated thermal shutdown and foldback current limiting - prevents damage during short-circuit or overload without external circuitry. |
| High PSRR & Low Noise | 60dB ripple rejection at 1kHz and 200µVRMS output noise - preserves signal integrity in noise-sensitive analog/RF stages powered by VOUT1/VOUT2. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS70251QPWPR | 3.3V/2.5V fixed outputs; higher 250mA per channel; larger 20-pin HTSSOP package (4.4mm × 6.5mm). | Requires PCB redesign due to pin count and footprint; suited for non-space-constrained industrial controllers. | Select when higher current or mixed-voltage rails are needed, not for 3.0V/3.0V portable designs. |
| AP7361-D-3030SA-7 | 3.0V/3.0V dual LDO; 300mA per channel; 8-pin DFN (2mm × 2mm); no independent enable pins (single EN). | Lacks per-rail enable control - limits sequencing flexibility in complex SoC power trees. | Choose only if board space permits larger package and single-enable operation suffices. |
Compared with TPS70251QPWPR and AP7361-D-3030SA-7, the MIC5370-PPYMT-TR uniquely delivers matched 3.0V/3.0V outputs with independent enable control in the smallest industry-standard footprint (1.6mm × 1.6mm), making it optimal for ultra-compact portable designs where rail independence and minimal board area are mandatory.

FAQ
What is the maximum input voltage rating for the MIC5370-PPYMT-TR?
The MIC5370-PPYMT-TR has an absolute maximum input voltage (VIN) rating of +6V, but its specified operating range is +2.5V to +5.5V. Operating within the 2.5V–5.5V range ensures guaranteed performance including ±2% output accuracy, 155mV dropout at 150mA, and thermal stability across –40°C to +125°C junction temperature.
Does the MIC5370-PPYMT-TR include output discharge functionality?
No, the MIC5370-PPYMT-TR does not include auto-discharge circuitry. That feature is exclusive to the MIC5371 variant (e.g., MIC5371-PPYMT). When disabled, the MIC5370-PPYMT-TR places its outputs in high-impedance state without actively discharging external capacitors - external bleed resistors may be required for rapid voltage decay.
Can the MIC5370-PPYMT-TR operate stably with no load on either output?
Yes, the MIC5370-PPYMT-TR remains stable and in regulation with zero load on either or both outputs. This no-load stability is confirmed in the datasheet and makes the device suitable for applications like CMOS RAM keep-alive circuits or standby power domains where one rail may be inactive while the other remains active.
What type of output capacitors are recommended for the MIC5370-PPYMT-TR?
X5R or X7R dielectric 1µF ceramic capacitors are recommended for both VOUT1 and VOUT2. These offer stable capacitance over temperature and low ESR, ensuring loop stability. Y5V or Z5U dielectrics are not recommended due to excessive capacitance drift (>50%) across operating temperature, which risks instability.
Is the MIC5370-PPYMT-TR pin-compatible with other variants in the MIC5370/1 family?
Yes, all MIC5370/1 variants - including MIC5370-PPYMT-TR and MIC5371-PPYMT - share identical 6-pin 1.6mm × 1.6mm Thin MLF® pinout and footprint. However, functional differences exist: MIC5370 lacks auto-discharge, while MIC5371 includes it. Swapping requires verification of enable/discharge requirements in the target application.
