The IXD1701 is positive voltage regulator with
operation voltage up to 28V, manufactured by CMOS
process.
The IC consists of a voltage reference, an error
amplifier, a current limiter, a thermal protection, a
phase compensation circuit, and a driver transistor.
The output voltage is selectable in 0.1 V increments
within the range from 1.8 V to 18 V. High precision
output voltage achieved by laser trimming
technology.
The IXD1701 is stable with low ESR ceramic output
capacitor (CL). The over current protection circuit and
the thermal shutdown are built-in. These two
protection circuits operate when the output current
reaches current limit level or the junction temperature
reaches temperature limit.
The Chip Enable (CE) function allows set IXD1701
into standby mode, reducing current consumption to
less than 0.1 µA typically.
The IXD1701 is available in SOT-25, SOT-89, SOT89-5, USP-6C, SOT-223, and TO-252 packages.
APPLICATIONS
Mobile phones
Car Audio and Navigation Systems
Cameras, VCRs

NOTE:
Unless otherwise stated, VIN = VCE = VOUT (T) +2.0 V
1) VOUT (T) is Nominal output voltage and VOUT (E) is Effective output voltage, (I.e. the output voltage when "VOUT (T) +1.0V" is provided at the
VIN pin, while maintaining a certain IOUT value).
2) VDIF = {VIN-VOUT}, where VIN1 is the input voltage when VOUT = 0.98 VOUT(T) appears, while input voltage gradually decreases
3) Refer to the Table “Voltage Chart, Output Voltage”

Product Specification
IXD1701
BASIC OPERATION
The Error Amplifier of the IXD1701 series monitors output voltage divided by internal resistors R1 & R2 and
compares it with the internal Reference Voltage (see Block Diagram above). The output signal from error amplifier
drives gate of the P-channel MOSFET, which is connected to the V OUT pin and operates as a series voltage
regulator.
The Current Limit/Short Protection circuits monitor level of the output current, and Thermal shutdown circuit
monitors MOSFET junction temperature to prevent IC damage by excessive current.
The CE pin allows shutdown internal circuitry to minimize power consumption.
Current Limiter, Short-Circuit Protection
The IXD1701 series have a current limiter circuit & a fold back circuit, which aid the operations of the current limiter
and circuit protection. When the load current reaches the current limit level, the fixed current limiter circuit activates
and output voltage drops. Because of this drop, the fold back circuit activates too, and output voltage drops further
decreasing output current. When the output pin is shorted, a current of about 30 mA flows.
Thermal Shutdown
When the junction temperature of the built-in transistor reaches the temperature limit, the thermal shutdown circuit
activates and turns transistor OFF. The IC resumes normal operation when the junction temperature falls below
value determined by Thermal Shutdown Hysteresis.
CE Pin
The CE pin allows shutdown internal circuitry to minimize power consumption. In shutdown mode, output at the
VOUT pin is pulled down to the VSS level by resistors R1 and R2 connected in series.
Note that the CE input is active HIGH and has no pull down resistor. IC will be in undefined state, if CE pin is open.
CE pin should be connected to either VIN or ground. IC current consumption may increase, if voltage applied to this
pin is ~ 0.5 of VIN.
Minimum Operating Voltage
The input voltage should be above 2.0 V for the stable IC operation.
TYPICAL APPLICATION CIRCUIT
LAYOUT AND USE CONSIDERATIONS
1. Mount external component as close to the IC as possible and use thick, short connecting traces to
reduce the circuit impedance.
2. The IC may malfunction if absolute maximum ratings are exceeded.
3. If power source of this regulator is a high impedance device, an input capacitor CIN ≥ 0.1μF should be
used to prevent oscillations.
4. The internal phase compensation guarantees the IXD1701 stable operations even without load
capacitor CL. However, load capacitor CL = 0.1 – 1.0 µF located as close to VOUT and VSS pins may
improve regulator’s dynamic characteristics, reducing over/undershoot at heavy load.
5. In case of high output current, increasing the input capacitor value can stabilize operations.
6. Please ensure that output current IOUT is less than PD / (VIN - VOUT), where PD is a rated power
dissipation value of the package shown at ABSOLUTE MAXIMUM RATING table to not exceed it.
7. If IC is operates at high temperature with no load, the output voltage may increase beyond nominal
range.
