Modeling low-dropout (LDO) regulators
This application note demonstrates how to model two basic types of LDO regulators and simulate their key characteristics.

This application note demonstrates how to model two basic types of LDO regulators and simulate their key characteristics.
Here is a tip on how to model transistors that behave as variable resistors.
This primitive generates a pseudo-random bit sequence, now with a new parameter 'seq_mode', defining whether the parallel stream is a MSB-first or LSB-first sequence.
This release adds a new 'seq_mode' parameter to the 'prbs_gen' primitive, and 'trig_mode' parameters to the 'meas_ber' and 'probe_ber' primitives.
