TCR5AM series
500 mA CMOS Ultra Low Drop-Out Regulator
The TCR5AM series are CMOS single-output voltage regulators
with an on/off control input, featuring Ultra low dropout voltage, low
inrush current and fast load transient response.
A differentiating feature is the use of a secondary bias rail as a
reference voltage that allows ultra-low drop-out of 90 mV (typ.) at
IOUT = 300mA ( 1.1 V output, VBAT = 3.3 V ).
These voltage regulators are available in fixed output voltages
between 0.55 V and 3.6 V, and capable of driving up to 500 mA.
Other features include over-current protection, over-temperature
protection, Under-voltage-lockout and Auto-discharge function.
The TCR5AM series are offered in the ultra small plastic mold
package DFN5B (1.2 mm x 1.2 mm; t 0.38 mm).
As small ceramic input and output capacitors can be used with the
TCR5AM series, these devices are ideal for portable applications
that require high-density board assembly such as cellular phones.
