300mA/500mA Low Noise CMOS LDO Regulators
ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.
VIN ..............................................................-2V to 6.0V
Output Voltage VOUT ...............................-0.6V to VIN +1V
Enable Input Voltage VEN................ .. ...............-2V to 6V
Storage Temperature .............................. -65°C to 150°C
Power Dissipation ............................... Internally Limited¹
Lead Temperature (Soldering, 5 sec) ................... +260°C
Junction Temperature ........................................ +150°C
OPERATING RATINGS
Input Voltage Range VIN.......................... +2.7V to +5.5V
Enable Input Voltage VEN................... ...............0 to 5.5V
Junction Temperature Range ................. -40°C to +125°C
Thermal Resistance ......................................................
SOT-23-5 (θJA) .............................................191°C/W
DFN-8 (θJA) ................................................... 59°C/W
Note 1: Maximum power dissipation can be calculated
using the formula: PD = (TJ(max) - TA) / θJA, where
TJ(max) is the junction temperature, TA is the ambient
temperature and θJA is the junction-to-ambient thermal
resistance. θJC is 6°C/W for this package. Exceeding the
maximum allowable power dissipation will result in
excessive die temperature and the regulator will go into
thermal shutdown mode.
ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Junction Temperature of TJ = 25°C only; limits applying over the full
Operating Junction Temperature range are denoted by a “•”. Minimum and Maximum limits are guaranteed through test,
design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for
reference purposes only. Unless otherwise indicated, VIN = (VOUT + 0.5V) to 6V, CIN = 2.2µF, COUT = 2.2µF and IOUT = 100µA,
TJ= –40°C to 85°C.
