Product details
Overview
TC1313-PP0EMFTR from Microchip Technology is a dual-output power management IC integrating a 500 mA synchronous buck regulator and a 300 mA low-dropout linear regulator (LDO) in a single 10-pin DFN package. It delivers 1.8 V @ 500 mA (buck) and 3.3 V @ 300 mA (LDO), with 2.0 MHz fixed-frequency PWM operation, 57 µA total quiescent current, and -40°C to +125°C junction temperature range - optimized for battery-powered portable computing and USB devices.
For engineers reviewing the TC1313-PP0EMFTR datasheet, TC1313-PP0EMFTR pinout, TC1313-PP0EMFTR application, or TC1313-PP0EMFTR equivalent, key selection criteria include independent shutdown control per rail, automatic PWM-to-PFM mode transition under light load, 137 mV LDO dropout at 200 mA, internal compensation eliminating external loop components, and UVLO/overtemperature/short-circuit protection across both outputs.
Technical Context
The TC1313-PP0EMFTR implements a current-mode synchronous buck regulator with integrated P-channel and N-channel MOSFETs (RDS(on) = 450 mΩ each), operating at 2.0 MHz (1.6–2.4 MHz range) under heavy load and transitioning automatically to pulse-frequency modulation (PFM) mode below ~30 mA output to maintain ultra-low quiescent current (38 µA typical). The LDO uses a PMOS pass device with 137 mV typical dropout at 200 mA and supports only fixed-output voltages (1.5 V, 1.8 V, 2.5 V, 3.3 V).
Both regulators are internally compensated and require no external compensation components. The buck output is adjustable (0.8–4.5 V) via external resistor divider on VFB/VOUT1, while the LDO output is factory-set - the "PP0" suffix in TC1313-PP0EMFTR indicates a 3.3 V LDO output. VIN1 and VIN2 are intended to be tied together, sharing a common 2.7–5.5 V input source.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output 1 Type | Synchronous buck regulator: delivers up to 500 mA with integrated high-side/low-side MOSFETs and 2.0 MHz switching. |
| Output 2 Type | Fixed-output LDO: 3.3 V nominal, 300 mA max, 137 mV dropout at 200 mA - enables low-input-margin bias rails. |
| Total Quiescent Current | 57 µA typical with both regulators enabled - critical for battery runtime in standby modes. |
| Operating Input Range | 2.7 V to 5.5 V on both VIN1 and VIN2 - compatible with single-cell Li-ion (2.7–4.2 V) and USB 5 V sources. |
| Junction Temperature Range | -40°C to +125°C - qualified for industrial and extended-temperature portable applications. |
| Protection Features | Undervoltage lockout (2.55 V typ.), thermal shutdown (165°C), overcurrent on both outputs, and short-circuit tolerance. |
| Package | 10-pin 3×3 mm DFN with exposed thermal pad - requires connection to AGND for thermal and electrical performance. |
Pinout & Package
TC1313-PP0EMFTR is housed in a 10-lead 3×3 mm DFN package with exposed thermal pad (EP), requiring solder connection to AGND for thermal dissipation and noise control. Pin numbering follows standard DFN orientation (pin 1 marked).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN2) | LDO shutdown control input | Active-high logic input; >45% VIN enables LDO, <15% VIN disables it - allows independent rail sequencing. |
| 2 (VIN2) | LDO input supply | Accepts 2.7–5.5 V; must be tied directly to VIN1 trace to minimize impedance and coupling. |
| 3 (VOUT2) | LDO regulated output | 3.3 V fixed output; requires ≥1 µF ceramic capacitor to AGND for stability and transient response. |
| 4 (NC) | No-connect terminal | Not bonded; must remain unconnected - no routing or pull-up/pull-down allowed. |
| 5 (AGND) | Analog ground reference | Low-noise ground return for feedback and control circuitry; separate from PGND in layout. |
| 6 (VFB/VOUT1) | Buck feedback or output sense | For fixed-output variants like TC1313-PP0EMFTR, this pin connects directly to VOUT1 (1.8 V); for adjustable versions, it accepts voltage divider feedback. |
| 7 (SHDN1) | Buck shutdown control input | Active-high logic input; independent of SHDN2 - enables discrete control of core vs. I/O rail power. |
| 8 (VIN1) | Buck input supply | Main power input for buck stage; shares same source as VIN2 but routed separately before tie-point. |
| 9 (LX) | Buck switch node | High-slew, high-current node connecting to external inductor; requires shortest possible trace and no vias. |
| 10 (PGND) | Power ground return | High-current return path for buck switching loop; must be isolated from AGND except at single point. |
Key Features
| Feature | Design Value |
|---|---|
| Independent shutdown per regulator | SHDN1 and SHDN2 allow staggered power-up/down sequencing - essential for FPGA or processor core/I/O rail timing control. |
| Automatic PWM-to-PFM mode transition | Eliminates need for external load detection circuitry; maintains regulation down to microamp loads while holding IQ ≤38 µA (buck only). |
| Internally compensated buck and LDO | Removes requirement for external compensation capacitors or resistors - reduces BOM count and board area by ≥4 passive components. |
| Low-noise 2.0 MHz switching | Enables use of small 4.7 µH inductors and 4.7 µF ceramic capacitors - supports compact layouts without EMI filters. |
| Thermal and fault protection | Integrated thermal shutdown (165°C), UVLO (2.55 V), and overcurrent limiting prevent damage during abnormal conditions without external monitoring. |
Applications
| Portable Medical Instrumentation | USB-Powered Peripheral |

Use Value: 3×3 mm DFN saves >60% board area versus MSOP alternative; single 1 µF LDO capacitor minimizes component count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65023BRSBR | Triple-output (2 buck + 1 LDO), higher IQ (100 µA), 2.25–6.5 V input, 3×3 mm QFN | Supports three rails; lacks independent LDO shutdown; requires external compensation for buck stages | Choose when third rail (e.g., memory I/O) is needed and higher IQ is acceptable. |
| RT8059ZSP | Dual buck (no LDO), 600 mA/600 mA, 2.7–5.5 V input, 1.5 MHz, 3×3 mm QFN | Provides two switching outputs only; no linear rail - unsuitable where low-noise 3.3 V is required | Choose only if both rails tolerate switching noise and higher efficiency at medium loads is prioritized. |
Compared with TPS65023BRSBR and RT8059ZSP, TC1313-PP0EMFTR uniquely combines a low-noise LDO with independent shutdown in a minimal 3×3 mm footprint and ultra-low 57 µA IQ - making it optimal for space-constrained, battery-sensitive dual-rail systems where one rail demands clean linear regulation.

FAQ
What output voltages does TC1313-PP0EMFTR provide?
TC1313-PP0EMFTR provides a 1.8 V buck-regulated output (VOUT1) and a fixed 3.3 V LDO output (VOUT2), as indicated by the "PP0" suffix. The buck output is set by internal feedback; the LDO output is factory-trimmed and requires no external resistors. Both outputs are specified across -40°C to +125°C junction temperature.
Can TC1313-PP0EMFTR operate from a single-cell Li-ion battery?
Yes, TC1313-PP0EMFTR supports input voltages from 2.7 V to 5.5 V, fully covering the discharge range of a single-cell Li-ion (2.7–4.2 V). Its 100% duty-cycle capability ensures the 1.8 V buck output remains regulated even at 2.7 V input, and the 137 mV LDO dropout allows 3.3 V output down to ~3.43 V input.
How is thermal management handled in TC1313-PP0EMFTR?
TC1313-PP0EMFTR incorporates thermal shutdown at 165°C with 10°C hysteresis and relies on its exposed thermal pad (EP) connected to AGND for heat dissipation. In a typical 4-layer board with internal ground plane and two vias, θJA is 41°C/W - enabling continuous 500 mA buck + 300 mA LDO operation at ambient ≤65°C without forced airflow.
Does TC1313-PP0EMFTR require external compensation components?
No, TC1313-PP0EMFTR features fully internal compensation for both the buck regulator and LDO. This eliminates external compensation capacitors and resistors, reducing bill-of-materials count and layout complexity - a key differentiator versus competing dual-output controllers requiring external loop tuning.
What protection features are integrated into TC1313-PP0EMFTR?
TC1313-PP0EMFTR integrates undervoltage lockout (UVLO at 2.55 V typical), overtemperature shutdown (165°C), output short-circuit protection on both rails, and overcurrent limiting. These functions operate autonomously without external circuitry, ensuring robust operation in unattended or harsh environments where TC1313-PP0EMFTR is deployed.
