Product details
Overview
LV59018M-TLM-H from SANYO Semiconductor is a 1.8V fixed-output LDO regulator with dual input supplies (VIN1/VIN2), active-high ON/OFF control via CTL pin, 1A output capability at VIN ≥ 2.8V, and ultra-low 1μA standby current. It integrates overcurrent and thermal protection and targets power-sensitive embedded systems requiring stable low-voltage bias.
For engineers reviewing the LV59018M-TLM-H datasheet, pinout, applications, or equivalent options, key selection factors include its dual-input architecture, 1.8V ±1.8% output accuracy over temperature, 0.4V dropout at 0.3A, 65dB ripple rejection at 1kHz, and MFP8 (200mil) surface-mount package compatibility.
Technical Context
The LV59018M-TLM-H employs Bi-CMOS process technology to achieve low quiescent current (110–160μA active, ≤1μA standby) while maintaining tight output regulation. Its dual-input design allows independent connection of signal- and power-system rails, with internal bandgap reference and current-limit circuitry enabling robust load transient response.
Thermal shutdown activates at junction temperatures exceeding safe operating limits, and overcurrent protection operates via foldback limiting. The CTL pin accepts TTL/CMOS-compatible logic levels (VCTLH ≥ 1.5V, VCTLL ≤ 0.3V) to enable/disable regulation without external pull-up/down components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 1.8V ±1.8% (1.767–1.836V at 10mA, –30°C to +85°C) |
| Max output current | 1A continuous (requires VIN1/VIN2 ≥ 2.8V) |
| Dropout voltage | 0.4V at 0.3A; 1.0V at 1A - defines minimum headroom for regulation |
| Standby current | ≤1μA when CTL = Low - enables deep power-down in battery systems |
| Ripple rejection | 65dB at 1kHz, 1Vpp input - suppresses switching noise from upstream DC/DC converters |
| Load regulation | 10–50mV over 5mA–1A load - ensures stable rail under dynamic CPU/peripheral loads |
| Line regulation | 10–50mV over VIN = 1.9–6V - maintains accuracy across wide input range |
Pinout & Package
MFP8 (200mil) 8-pin molded flat package with exposed radiation pad (GND-connected or floating per layout); 5.0mm × 4.4mm footprint, 1.7mm max height; RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN1 | Power system supply input | Primary high-current input rail; must be ≥2.8V for full 1A output |
| 2 - NC | No connect | Internally unconnected; leave unpopulated or float |
| 3 - VIN2 | Signal system supply input | Secondary input for noise-isolated bias; shares regulation path with VIN1 |
| 4 - CTL | Active-high enable control | Drives internal pass transistor gate; ≥1.5V enables output, ≤0.3V disables |
| 5 - NC | No connect | Internally unconnected; leave unpopulated or float |
| 6 - VO | Regulated 1.8V output | Delivers up to 1A; requires ≥4.7μF ceramic output capacitor for stability |
| 7 - NC | No connect | Internally unconnected; leave unpopulated or float |
| 8 - GND | Ground reference | Common return for all inputs, control, and output; connects to radiation pad |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent input rails | VIN1 and VIN2 accept separate power domains (e.g., main supply + low-noise signal rail), reducing coupling between noisy and sensitive subsystems |
| Ultra-low standby current | ≤1μA shutdown current enables multi-year battery life in always-on sensor nodes and real-time clocks |
| Integrated protection | Thermal shutdown and current-limiting prevent damage during overload or ambient temperature excursions beyond –30°C to +85°C |
| Tight output accuracy | ±1.8% initial tolerance and ±100ppm/°C tempco ensure reliable logic-level compliance for 1.8V I/O interfaces |
| High PSRR at 1kHz | 65dB ripple rejection minimizes conducted noise from switch-mode power supplies feeding the LDO input |
Applications
| Mobile Baseband Processors | Industrial PLC I/O Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0518PDBVR | Single-input (VIN only), 1.8V output, 200mA max, 0.25V dropout at 200mA, 25μA IQ | Limited to lower current; no dual-rail support; smaller SOT-23-5 package | Select when board space is critical and load current ≤200mA; not suitable for 1A applications. |
| XC6210B182MR-G | Single-input, 1.8V output, 1A max, 0.35V dropout at 1A, 1.5μA standby, SOT-25 package | Lacks dual-VIN architecture and CTL pin; uses active-low EN; no integrated thermal shutdown | Choose for cost-sensitive 1A designs where dual-supply isolation is unnecessary and external thermal monitoring exists. |
Compared with LV59018M-TLM-H, TPS7A0518PDBVR offers smaller size but insufficient current drive, while XC6210B182MR-G matches output current and standby current but omits dual-input flexibility and integrated thermal protection - making LV59018M-TLM-H preferable for thermally constrained, multi-rail embedded systems.

FAQ
What is the maximum allowable input voltage for LV59018M-TLM-H?
The LV59018M-TLM-H supports absolute maximum input voltage of 6.2V on both VIN1 and VIN2 pins. Operation above this level risks permanent damage. For reliable long-term use, keep VIN1 and VIN2 within the recommended range of 1.9V to 6.0V, especially when delivering 1A output current.
Can LV59018M-TLM-H operate with only one input supply connected?
Yes, LV59018M-TLM-H can operate using either VIN1 or VIN2 alone, though both are designed to be connected for optimal performance. If only one is used, ensure it meets the minimum 2.8V requirement for full 1A output capability and that the unused pin is left open (not shorted or grounded).
What is the purpose of the radiation pad on the LV59018M-TLM-H package?
The radiation pad on the LV59018M-TLM-H is a high-impedance substrate connection point. Per SANYO's recommendation, it should be connected to GND for improved thermal dissipation and EMI suppression, or left unconnected (open) if thermal constraints permit. It must never be tied to a voltage rail other than GND.
Does LV59018M-TLM-H require an external output capacitor, and what value is recommended?
Yes, LV59018M-TLM-H requires a minimum 4.7μF ceramic output capacitor placed close to the VO and GND pins for stability. A 10μF capacitor is recommended for improved transient response and ripple suppression. Use X5R or X7R dielectrics with low ESR (<100mΩ) and ensure proper PCB layout with short, wide traces.
How does the CTL pin behavior affect system power sequencing?
The CTL pin on LV59018M-TLM-H is active-high: applying ≥1.5V enables the output, while ≤0.3V disables it, reducing current draw to ≤1μA. This allows precise control of power-up/down sequencing in multi-rail systems - for example, enabling LV59018M-TLM-H only after primary supplies stabilize - without requiring external MOSFETs or sequencers.
